Fabrication and Properties of WhiteLuminescence Conversion LEDs

TANG Ying jie, WANG Yu fang, YANG Zhi jian, ZHANG Guo yi(Department of Physics, Mesoscopic Physics National Key Laboratory, Peking Un iversity, Beijing100871, China)  
The white light emitting diodes (LEDs) were fab ricated by using InGaN based blue LED chip as primary light source and Y 3Al 5O 12 (yttrium aluminum gar net) phosphors as luminescence conversion materials. To achieve packaged LED dev ices, the diode chips were encapsulated in transparent epoxy resin. At room temp erature and I f=20mA, the luminous intensity is about 170mcd. The current d ependence of both the emission spectrum and intensity was measured and discussed
