12 January 2005 Fabrication and properties for white LED with InGaN SQW
Author Affiliations +
High brightness white light-emitting diode (LED) was fabricated by using the self-produced InGaN single quantum-well (SQW) blue LED chip and YAG:Ce3+ phosphor. The luminous intensity of the white LED was up to 2.3cd, the chromaticity coordinate was (0.28,0.34), and the color-rendering index was about 75 at forward current of 20mA and room temperature.
