摘要：

Cathode ray excitation of X2–Y2SiO5:Eu3+ results in a moderate red emission. The efficiency is enhanced considerably (≈ 700%) by the simultaneous introduction of a high Tb3+ concentration (e.g. YTbSiO5:Eu3+). An enhancement of the photoluminescence emission is observed as well. The luminescence properties are studied as a function of the Tb3+ content. The mechanism of energy transfer in cathodo‐ and photoluminescence are discussed. Copyright © 1990 WILEY‐VCH Verlag GmbH & Co. KGaA
