Effect of magnesium on the performance characteristics of ZnS:Cu,Mn phosphors

We have studied the effect of magnesium added to the starting mixture as MgS or MgCl 2 on the performance characteristics of synthesized ZnS:Cu,Mn phosphor powders.

Zusammenfassung:We have studied the effect of magnesium added to the starting mixture as MgS or MgCl 2 on the performance characteristics of synthesized ZnS:Cu,Mn phosphor powders. It has been shown that the incorporation of certain amounts of magnesium into the ZnS:Cu,Mn phosphor leads to an increase in photo- and electroluminescence brightness and is favorable for Mn incorporation into the structure of the phosphor. In particular, additional doping of a dc electroluminescent ZnS:Cu,Mn phosphor with 30 mol % Mg ensured not only a shift of its luminescence spectrum to shorter wavelengths, thereby extending the color range of light sources, but also a twofold increase in its brightness.
