چکیده انگلیسی
A novel red phosphor, CaMoO4:Eu3+, has been developed for white light emitting diodes (LEDs). The phosphor was prepared by using oxides in air and its luminescent properties have been investigated. The excitation and emission spectra indicate that this phosphor can be effectively excited by ultraviolet (UV) (394Â nm) and blue (464Â nm) light, and exhibits a satisfactory red performance (616Â nm), nicely fitting in with the widely applied UV or blue LED chips. The novel phosphor is much more stable and has stronger emission intensity than the sulfide red phosphors used in white LEDs.
