摘要：

Investigations on the degradation behavior of LaOBr:Tb phosphors under cathode-ray excitation are presented. The microscopic nature of defects created under prolonged electron bombardment has been identified using extended optical analyses on aged LaOBr:Tb phosphor screens and supported by ion desorption experiments performed in an ultrahigh vacuum system. The degradation behavior of LaOBr:Tb can be improved considerably by codoping this phosphor with chloride or iodide.
