Abstract
The quantum efficiency results of a new air stable organic semiconductor UV photocathode P3DDT are presented in this paper.Measurement of QE was carried out as a function of wavelength in spectral region 190-250nm. It shows cut off near 230nm. However, QE is too low to be of interest as compared to CsI but being air stabile and easyto prepare photocathodeswith large area it can find applications in barium flouride scintilation based calorimetry and plasma diagnositic where photon flux is very high.
