Abstract:

ZnO-based Phosphors were prepared by sintering. The properties were characterized by XRD and SEM. The results show that ZnO:Zn phosphor with great crystalline and small grain size was prepared by calcining with NH4Cl as flux. It gives a broadband green luminescent emission with excitation wavelength 387nnm. Eu3+-doped ainc oxide were sintering at 800℃. The Eu3+ ion reduced the sintering temperature to some extent. The fluorescence emission peak wavelength of ZnO:Eu is at 700nm with excitation wavelength 465nm.

Key words: materials, phosphor, ZnO:Zn2+, ZnO:Eu3+, fluorescence property
