Abstract. This paper presents new and possible industrial applications of II-VI semiconductor compounds. In the recent years, wide gap II-VI compounds have considerably been utilised in the electronic applications. Having higher optical transition probabilities for absorption and luminescence, higher ionicity, smaller radiative lifetime, II-VI semiconductor materials such as CdS, CdSe, CdTe, ZnS, ZnSe, ZnO, have been capable of emitting every colour of the visible spectrum in the LED production. Moreover, the information transfer devices, solar energy converters, photoresistors, X-ray detectors and also electron beam screens have been the domain of II-VI compounds, because these materials can be produced to a high standard of purity from inexpensive and available raw materials. II-VI compounds can be produced in the form of polycrystalline layers of good optical quality by means of convenient and cheap methods as well. The surfaces and interfaces of these compounds are commonly rather stable. Because of that these semiconductors have been seen as significant rival materials against elemental other group semiconductor compounds.
