Japan Develops Si-based LED Using Ge Quantum Dots

The Research Center for Silicon Nano-Science (SNS) of the Advanced Research Laboratories (ARL) at Tokyo City University developed a silicon-based LED. It is made by embedding Ge microparticles (quantum dots) with a diameter of several tens of nanometers to 100nm in the i-layer of a Si-based device with a pin structure. The university claims that the light emitting device will help realize a silicon (Si) photonics because it can be produced by using a manufacturing process compatible with a CMOS process and possibly is capable of laser oscillation.

Japan Co FujiFilm Develops Light Diffusing Film for LED Lighting

Japan's Fujifilm Corp. plans to enter the market for LED lighting materials with a new kind of light diffusing film which is thinner and offers higher illumination intensity than products now available. The light diffusing film acts to spread out the light from the LED bulbs so they are not so bright. These diffusers are now typically made from acrylic resin materials which are milky in color and around 2mm thick. The thickness means they are hard to bend, and the milky color means that some of the light is wasted.
