Abstract
Nanocrystalline phosphors were synthesized by a Pechini-type sol-gel process. Under UV and electron-beam excitation, show the characteristic emission of and , respectively. In particular, the cathodoluminescence (CL) color of can be tuned from blue to green by changing -doped concentration, and their CL intensities (brightness) are higher than those of commercial products and ZnO:Zn, respectively. White CL can be realized by codoping with and in a single-phase LaOCl host. The obtained white light is very close to the standard white light. These phosphors are promising for application in field-emission displays.
