The nature of the luminescence of zinc sulfide in the spectral range (360), 380-420 nm (SAL) at 80‡K is analyzed. It is shown that the appearance of SAL radiation is accompanied by additional absorption in the region (350) 365-370 nm at 80‡K. The low-temperature spectra of sphalerite, exposed to different radiation and subjected to different treatment, are studied. The multiband luminescence of the isoelectronic sulfur impurity in ZnO deposits in the region 383-640 nm is discussed. It is concluded that SAL luminescence is attributable to the localization of excitons in ZnS on clusters, whose formation precedes the precipitation of the ZnO·S phase. The formation of oxygen clusters and deposits on dislocations in ZnS is studied. [ABSTRACT FROM AUTHOR] |
