【Abstract】 The CsI/Au/LiF FUV photoemissive characteristics have been studied in the paper. The eigenemissive average quan-tum efficiency is 15-18% electron/photon in the wavelengths ranging from 105 nm to 167 nm. The results obtainedfrom ESCA indicate that the CsI layer has high compatibility with the Au film before and after the annealing treatment inair for 0. 5h at 423K. The threshold of photoemission decreases with C and 0₂ contamination amount on the surface ofCsI.更多还原
