摘要

本文报道了一种新型空气稳定有机半导体紫外光电阴极P3DDT的量子效率结果。在190 ~ 250nm光谱范围内测量了QE随波长的变化。它显示在230nm附近切断。然而，与CsI相比，QE太低而无法引起人们的兴趣，但由于它具有空气稳定性并且易于制备大面积光电阴极，因此可以在基于氟化钡闪烁的量热法和等离子体诊断中找到应用，其中光子通量非常高。

Investigation of External QE of P3DDT Photocathode for use in Gaseous UV Photon Detectors

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.
