In order to enhance the spectral red intensity of the white LEDs,which are adapted to eye vision,the Gd3+ and Pr3+ are doped into the YAG:Ce phosphor.Thus the spectra of white LEDs appear a new red peak at about 610 nm and the fluorescent main peak has been red-shifted.The color coordinates of LEDs are calculated.The results show that the color coordinates of the new white LEDs fabricated by new phosphor can produce standard white point(0.33,0.33),while the ordinary LEDs encapsulated by the YAG:Ce phosphor ...
