A Novel Red phosphor for White Light Emitting Diodes. — The new red phosphor
3+
for white light emitting diodes is prepared by solid state reaction in air
4:Eu
22- 010 CaMoO
from stoichiometric mixtures of MoO3, CaO, and Eu2O3 (700 °C, 3 h). The samples are
characterized by XRD and excitation and emission spectroscopy. This phosphor can be
effectively excited by UV (394 nm) and blue (464 nm) light, and exhibits a satisfactory
red performance (616 nm). The novel phosphor is much more stable and has stronger
emission intensity than the sulfide red phosphors used in white LEDs. — (HU, Y.;
