| Rezumat | ||||||
A significant anisotropy of photoluminescence was found in ZnIn2S4:Cu and
ZnIn2S4:Mn single crystals. Polarization in perpendicular directions changes the recombination mechanism. It was shown that the peculiarities of the investigated photoluminescence
spectra are associated with the optical transitions involving donor and acceptor levels. The
possibility was found to control the spectra shape and intensity using doping and variation of
technological parameters that allows preparing single crystals with alternation of three and
one packet polytypes. This is promising for practical applications. |
