Work was started in purifying the best commercially available CdSe powder, and in studying the effect of Zn impurities on the photoelectronic characteristics of sintered CdSe layers. A literature search is being made on other new PC materials for possible use in the PC-EL image intensifiers. An effort was made to diminish the high noise level in the Hall-effect measuring device. Several batches of CdSe PC powders were made. The effect of copper and oxygen acceptor concentration was studied in these powders. Evaporated EL films were studied with MgF2 insulating layers above andor below the EL films. Life tests on differently prepared EL films did not show any useful improvement. An increased effort in building high resolution image intensifiers was started. Author
