c and cadmium compounds are all direct semiconductors. Thus the need to conserve crystal momentum does not inhibit band-to-band radiative recombination and the II–VI semiconducting compounds are efficient emitters and detectors of light. It was as phosphors for CRT displays that these materials first found application.

A Review of the Growth of 3D II-VI Compoundsso had some interesting developments, showing significant increases in rate, due, apparently, to the use of hydrogen as a transport agent. Other techniques have not kept pace with developments in melt and vapor growth.

Frequency Dependence of Interband Two-Photon Absorption Mechanisms in ZnO and ZnSrst experimental evidence of a dominant mechanism of forbidden-forbidden type has been obtained. Furthermore, the spectral behaviour of the TPA coefficient (α.) has been well described by a parametric formula containing terms (with different energy dependences) related to the above-mentioned different transition mechanisms.
