Abstract

Ageing results of N,N?-Bis(3-methylphenyl)-N,N?-diphenylbenzidine (TPD) and 8-Hydroxyquinoline (Alq3) are presented in this work. Photocathodes were investigated under accumulated photon and ion bombardment. QE of degraded photocathodes were compared with QE results of freshly prepared photocathodes. Negligible change in QE of photocathodes was observed as compared to the results of CSI photocathodes under similar experimental conditions.
