Abstract We have investigated the influence of water molecule absorption on photoemissive and structural properties of potassium bromide (KBr) thin film photocathode under humid air exposure at relative humidity 62 ±3%. It is evident from photoemission measurement that the photoelectron yield of KBr photocathode is degraded exponentially with humid air exposed time. Structural studies of the “as-deposited” and “humid air aged” films reveal that there is no effect of relative humidity on film׳s… Expand
