Abstract
Using the characteristics of electron trapping material (ETM) for the rapid infrared upconversion, a kind of novel combined infrared photocathode was made by coupling ETM-based infrared upconversion screen with visible photocathode. The present experiment showed that the combined photocathode is able to extend spectral sensitivity to 0. 8-1.6μm and make time resolution better than 24ps, and minimum detectable energy density less than 4, 8×10-9J/mm2.
