Abstract
Spectral energy distribution and luminous efficiency measurements of Zn2SiO4:Mn and of various samples of (Zn, Be)2SiO4:Mn are reported. Quantum efficiencies of these phosphors under 2537A excitation are calculated from this data. The introduction of beryllium into alphawillemite causes a decrease of the ``green'' luminescence band of this phosphor and the growth of a new emission band with a peak in the neighborhood of 6100A, the high quantum efficiency being preserved. The general role of manganese as an activator is considered, and the resulting picture used to explain the effect of beryllium and other substituents for Zn+2 or Si+4 on the spectral properties and on the luminescence decay of manganese‐activated materials.This publication has 8 references indexed in Scilit:
