摘要：
The fluorescence spectra of Eu3+ and Tb3+-doped YOCl, LaOCl, GdOCl, (La,Gd)OCl, (La,Y)OCl and (Gd,Y)OCl powder phosphors are reported and they are analysed by evaluating the colour coordinates ((X) over tilde, (Y) over tilde) and also the relative fluorescence intensity ratios (R). The Eu3+ :phosphors have displayed bright red emission (D-5(0), F-7(2)) and Tb3+ : phosphors green emission (D-5(4) --> F-7(5)) under an UV source. (C) 1999 Elsevier Science S.A. All rights reserved.
