| Abstract: | It is reported that the white light emitting diodes are fabricated by combining Ce3 :YVO4 fluorescence and InGaN/GaN blue LED. At forward voltage Vf=3.5V, forward current If =20mA, and room temperature, the luminous intensity of the white LED is 1cd, and the chromaticity coordinate (x, y) (0.32, 0.37) , which is near to the pure white (0.33,0.33). |
