Reversible Creation and Annihilation of a Violet Fluorescence Band in Doped ZnS Crystals Open
Annealing of doped (Cu, Ag, Au) ZnS crystals at 1200 °C and subsequent quenching or slow cooling, respectively, create or annihilate a violet fluorescence band, reversibly. The experimental results indicate that the emission must be due to…

Thermolumineszenz von kubischem und hexagonalem ZnS/Cu / Thermoluminescence of Cubic and Hexagonal ZnS/Cu Open
The emission spectra, thermoluminescence glow curves and thermoluminescence spectra of cubic and hexagonal ZnS/(10 -4 )Cu phosphors were measured comparated to these of ZnS/ (5·10 -4 ) Cu phosphors by excitation with light. The shape of th…

Thermoluminescence of ZnS Open
A number of zinc sulphide phosphors containing cobalt was prepared with various concentrations of additional impurities. Co ++ -ions in both copper and silver activated phosphors produce a characteristic glowcurve, showing three distinct p…

Zur Lumineszenzschädigung von ZnS/Cu Open
The resistance to radiation damage of the blue and green emission bands of ZnS/Cu is found to vary with mass, energy and dose of incident ions. The experimental results are discussed with Schön’s kinetic model and our proposed model for lu…
