“…Tb 3þ þ Li þ : This is in accordance with the charge compensation theory given by Kroger and Hellingmann [22]. Thus, the absence of 150 1C TSL peak in ZnAl 2 O 4 :Tb,Li phosphor is ascribed to the absence of V centre.…”

“…It is well known that introduction in A II B VI compounds of group IB elements (Cu, Ag, Au, usually called activators) and group III elements (Al, Ga, In, usually called coactivators) results in specific emission bands [15]. Kröger and Hellingman have been suggested an explanation about possible role of activators and co-activators on the basis of charge compensation mechanism [16].…”

Thin films of ZnS were grown by metal‐organic chemical vapor deposition (MOCVD) method under atmospheric pressure onto glass substrates. ZnO–ZnS:[Ag, Ga] and ZnO:[Ag, Ga] thin films were prepared by oxidation and Ag, Ga doping of ZnS films at temperatures of 700–775 °C for 0.5–1 h. Crystalline quality and luminescent properties were investigated using X‐ray diffraction (XRD), atomic force microscopy (AFM), and photoluminescence. It is found that the doped films have a polycrystalline structure without preferred orientation and consist of small grains gathered into conglomerates. The shape of photoluminescence (PL) spectra of the films depends strongly on the preparation conditions. The ZnO–ZnS:[Ag, Ga] films exhibited the blue and green emission connected with the presence of silver and oxygen, respectively. The ZnO:[Ag, Ga] films revealed the white emission originated from different defect‐related transitions. The possible origin of radiative centers is discussed (© 2012 WILEY‐VCH Verlag GmbH & Co.

“…A number of papers on the mechanism of luminescence were presented. These included the works by Kroeger and Hellingman 16 and by Smith 17 who reported on the properties of sulphide phosphors. Garlick and Mason 18 who worked on thermoluminescence ͑TL͒ of phosphors discussed the correlation between the impurities in zinc sulphide phosphors and the trap depths.…”
