摘要: Nanocrystalline LaOCl:Tb3+/Sm3+ phosphors were synthesized by a Pechini-type sol-gel process. Under UV and electron-beam excitation, show the characteristic emission of Tb3+ (5D3,4→7F6,...2) Sm3+ (4G5/2→6H5/2,7/2,9/2), respectively. In particular, cathodoluminescence (CL) color LaOCl:Tb3+ can be tuned from blue to green changing Tb3+-doped concentration, their CL intensities (brightness) are higher than those commercial products Y2SiO5:Ce3+ ZnO:Zn, White realized codoping with in single-phase LaOCl host. The obtained white light is very close standard light. These promising for application field-emission displays.
