A New Materials Printer Deposits Functional Fluids
The Fujifilm Dimatix DMP-3000 materials deposition printer offers users a larger format, higher accuracy and higher repeatability.

A third endorsement comes from Ghassan Jabbour, director of research, optoelectronic materials and devices at the Flexible Display Center at Arizona State University. “The new DMP-3000 provides an increased printable area and higher stepping accuracy and repeatability. Also, having the flexibility to interchange printheads of varying drop sizes as needed is an important and unique advancement in this area.”

Roland Piquepaille at ZDNet has a post on OLED lighting reportedly achieving 100% energy efficiency.
You all know that incandescent light bulbs are terribly inefficient, turning only 5% of the electricity they consume into light. Fluorescent lamps are better using up to 25% of its energy as light. And solid state lighting devices lose only 50% of the energy they received. But now, researchers at Arizona State University (ASU) claim they’ve developed organic lighting devices which are 100% efficient. The researchers think it’s possible to produce these solid-state lighting devices based on OLED technology at low cost. If this is true, this would be of major benefit to the environment by conserving energy and natural resources.
These organic lighting devices have been developed by a team led by Ghassan Jabbour, professor at the ASU School of Materials, and Jian Li, an assistant professor in the same department. In addition, Jabbour is director of optoelectronics research and development at the Flexible Display Center at ASU.
What’s particularly significant about the researchers’ work is that their optimized device adopts an even simpler structure than any yet reported by other research groups. “There is no waste of electricity,” Jabbour says. “All the current you are putting into the device is being used to produce light. It’s the first time something like this has been demonstrated. Nobody else has shown a 100 percent internal quantum efficiency for lighting devices using a single molecular dopant to emit white light.”
This research work has been published in Advanced Materials under the name “Excimer-Based White Phosphorescent Organic Light-Emitting Diodes with Nearly 100 % Internal Quantum Efficiency” (Volume 19, Issue 2, Pages 197-202, January 2007). Here are two links to the paper reference and a short comment about it. “By combining the monomer and excimer/aggregate emission of FPt, a white OLED can be obtained. Incorporating the novel host material 26mCPy and engineering the charge balance properties, Jabbour and co-workers used FPt to demonstrate, for the first time, nearly 100% internal quantum efficiency in white OLEDs.”

as the above was printed in 2007, I wonder how close it is to an actual product or if it’s already passé due to the QLED?

"But our vision is that it is really easier to integrate the materials and the cloth, not make the cloth itself," Jabbour said.

"This sounds like science fiction, but lots of things we have today were science fiction yesterday," says Ghassan E. Jabbour, associate research professor of optical sciences at the University of Arizona."Some of the research we do is high risk, but if successful, the payoffs are huge."
Jabbour is pioneering flexible organic and polymeric electronics and photonics (optical electronics) - a technology based on new, ultra-thin organic films that either function as transistors, emit light, or in the case of solar cells, collect light to generate electricity.Jabbour and his group, along with European partners, are developing nanometer-thick organic films for printing on paper, plastic and textiles.These films could be manufactured on flexible substrates by the mile, rolling like reams of newspapers off a cylindrical press.
"Our goal really is to print these nanofilms using traditional tools like screen printing, inkjet printing, laser printing, and gravure printing.Printing all these nanofilms by traditional techniques reduces cost and is one of the major reasons why this is really attractive," Jabbour said.
His laboratory was the first to print organic light-emitting devices on large areas of plastic and textile by screen printing. His group also found a unique technique to inkjet print using this technology as well.
About six months ago, Jabbour and his team demonstrated that such nanofilms could be printed on cloth.Theirs is the first such breakthrough.
"We now know how to integrate organic materials onto textiles.We haven't solved the whole problem yet, but we understand the pitfalls, what the 'killers' are that prevent these materials from sticking to cloth."
Jabbour collaborates with other UA optical scientists and materials scientists on integrating ultra thin organic films for memory storage and other applications.
...
Jabbour adds a couple of caveats about university research on new photonic materials and new processes to print organic and hybrid electronics.
One is that university researchers study the science that supports development of new emerging technologies.Industry - and industry is heavily interested, Jabbour says - recognizes potential applications and products that can profitably be developed from academic research.That university research focuses on basic science and industry focuses on applications is a point that people sometimes fail to grasp.
Two is that applications of many new technologies are niche applications - they are appropriate for many great new things, but won't soon replace established technologies that continue to improve.
Case in point: "Organic nano-thick film technology is not about to replace silicon," Jabbour said."Based on current materials, organic solar cells won't out-generate silicon solar cells soon.I strongly doubt you will see space shuttles using this technology, at least for the next several years.However, organic solar cells have many attractive attributes that make them suitable replacements for their inorganic counterparts in some cases," he added.
