A method of determination of Mn concentration in ZnS:Mn based on existence of two manganese kinetic components is proposed. In the method the manganese concentration is determined by lifetime and initial intensity of electroluminescence measurements. The results of the measurements are compared with statistical distributions of single Mn^{2+} ions and Mn^{2+} -Mn^{2+} pairs in hexagonal ZnS.

Electrical and luminescent properties of ZnS:Mn,Cu,Cl thin films were investigated. Combined both studies: scanning tunneling microscopy and scanning tunneling spectroscopy were made. The current and differential conductance versus applied voltage were measured for the ZnS:Mn,Cu,Cl thin films. Additionally, the spectral and kinetic properties of the electroluminescent cells based on the ZnS:Mn,Cu,Cl thin films were measured. The maximum of the electroluminescence lies at 586 nm. The electroluminescence was excited by rectangular wave voltage pulses with pulse length from 1μs to 1 ms. It was shown that time dependence of the electroluminescence is well explained assuming energy transfer between monomolecular centres.
