UC Santa Barbara researchers have created the very first monolithic and transparent blue-emitting phosphor that takes UV light and transforms it into blue light.
Light-emitting diodes (LEDs) are rapidly replacing traditional incandescent and fluorescent lighting. Laser diodes (LDs) also have a significant impact on the lighting market and offer increased peak efficiencies at higher increased operating currents than LEDs. Currently, both LEDs and LDs are being investigated as sources to generate white light using inorganic phosphors.
UC Santa Barbara researchers have created the very first monolithic and transparent blue-emitting phosphor that takes UV light and transforms it into blue light. By using spark plasma sintering (SPS), one can create non-encapsulating monolithic phosphors in only 30 minutes, much faster than currently practiced techniques. Due to the monolithic characteristic and the elimination of encapsulating materials, this blue-emitting phosphor technology is perfectly suited to improve upon LEDs and LDs. Since this is the only monolithic blue-emitting phosphor technology able to handle the high heat of LEDs and LDs it proves quite promising for the next generation of lighting.
