Summary UV detectors comprising undoped Zn1-xMgxS as the UV responsive active material. Where x exceeds 0.3 the thickness of the active material must be below a critical value, for example if 0.30<x<1.00, and the active material is formed as a layer of a thickness t wherein 5000 Å≥t≥100 Å. A particularly preferred combination of x and thickness is x=0.57 and t≤1400 Å because at around these values the UV response of the active material is similar to the UV response of human skin.
