Cathodoluminescence of Air, Quartz and Metal Films

THE luminescence of air and fused quartz under α-particle irradiation has been observed previously using a photomultiplier1. The luminescence spectra of these and other materials excited by 100-keV. electrons have now been studied with a quartz spectrograph. The electron beam was obtained from a discharge tube, fitted with a metal Lenard window, the… CONTINUE READING
