Abstract

In the work there are submitted the results of the research of photosensors on a base of solid solutions of A(superscript II)B(superscript VI) compounds for measurement and control of intensity of low-level light in narrow areas of spectrum. The basic principles of technological process of manufacturing of injection photo diodes are described. The results of measurements of voltage-current characteristics and spectral characteristics of photo diodes, received in laboratory technological process with the various contents of cadmy and zinc in ZnCd(subscript 1-x)S(subscript x) solid solutions, and also sulfur and selen in CdS(subscript 1-x)Se(subscript x) solid solutions are submitted. The investigation results have shown, that photosensors work at low positive bias voltage, do not require cooling, have high sensitivity in a maximum and narrow selectivity. In CdS(subscript 1-x)Se(subscript x)- photosensors the photosensitive protecting coverage of transparent films on the base of As(subscript 2)S(subscript 3) compounds is applied. The opportunity of creation of a wide discrete range of photo diodes with the sensitivity in range from near ultraviolet up to near infrared area of spectrum is shown.
