The optimal technological regime of formation ZnS_1–xTe_x solid solution at spacing 0,0≤х≤0,1 has been determined, and has been shown that fritting in hydrogen atmosphere results in more rapid reaction in comparison to argon due to chemical-thermal etching the ZnO layer out. Further annealing in the inert Ar atmosphere leads to the increase of the light output, to the intensive emission band formation and causes afterglow level reduction and the crystalline lattice rearrangement.
