A new generation of lighting materials and carbon materials has attracted much attention

Rise in the LED lighting market, the development of organic EL lighting progressively advances a new generation of lighting high-profile cases, through the adoption of new materials to improve performance, with flexibility to develop its special purpose to try more and more.

in the 'new material' Japanese channel 2009 top news, white leds with SiAlON class phosphor material in practical application. Compared with the original silicate materials, SiAlON class material brightness and color relative to the change of the temperature rise is small. Is expected for LCD back light and LED lighting, billions of yen/year of operations.

the fifth was USES the transparent resin instead of ITO electrode and high conductivity is developed flexible organic EL lighting panel. Implementation flexibility can be used to create a new concept of product, but for that need in the resin film film at low temperature. And ITO in conductivity can't improve the problems existing in the low temperature process. According to introducing, in the trial production by means of PEDOT/PSS ( 3, 4 - Two oxygen ethylene thiophene/poly styrene sulfonate) 4 Transparent resin, 'conductivity by about 6 times.

in 2009, is not only a new generation of lighting research progress of PEDOT/PSS materials research also made progress. Bridgestone, for example, in a speech in 'SIDDisplayWeek2009' seminar, announced that the company's electronic paper with transparent ITO electrode instead of PEDOT/PSS practical has begun. Japan yamanashi university have successfully developed transmission rate was 89%, the conductivity of up to 443 s/cm PEDOT/PSS membranes, the university, said in the previous published the transparency of close to 90% of PEDOT/PSS membranes, the products meet the highest electrical conductivity. In the future, instead of ITO PEDOT/PSS materials will accelerate the trend.

can let a person feel carbon nanotubes ( CNT） Graphene and carbon new material used in electronic components research is steadily promoting news is fourth Fujitsu this exposition 'international nanotechnology ZongGeZhan ( NanoTech2009） 'Report.

previously mentioned carbon materials, mostly is the study of the channel layer USES the CNT transistor, has now started to use a variety of carbon materials such as graphene. Graphene is benzene ring is connected to the honeycomb six-member ring chips, channel layer using graphene transistor has the advantages of high carrier mobility, easy to manufacture.

CNT, in addition to the transistor, used for convex block ( 撞) As well as the wiring and so on further considering the practical application of the research is quite notable. If the CNT to convex pieces, even if is the thermal stress and mechanical stress, LSI is not easy to damage, and could be used to heat and inductors. Used in wiring, hope the CNT can replace subtle change cannot smoothly even after the further development of copper wiring ( Cu） 。
