The problem of a decomposition of the integral PL spectra on individual components is an actual problem now. For today there are various methods of its decision but, unfortunately, all from them is far not yield comprehensible results and can be used in real experimental conditions. For the example, well-known Alenzev method [1] is requiring to use at once the several PL spectra that are received under various experimental conditions. Moreover these spectra must have significant differences from each other by the form. Mathematical methods [2] often are convenient in application, but necessarily required a special estimation of the error that may arise at their using. The experimental method "λ - modulations " [3] is supersensitive and, basically, allows to find out even phonon replicas. However, for the same reason it is unstable to influence of external handicaps. The main goal of this work was to get of the direct experimental information about individual PL bands of ZnS:Mn single crystals with help of the pulse excitation method of samples and the subsequent registration of the glow centres at the certain stages of afterglow. Such method has shown high efficiency at the room temperature without any preliminary processing a signal. It has allowed to find out individual PL bands with the width of a peak at the half of maximum amplitude - 0,015 ÷ 0,020 eV. The sense of this method consists in that that each type of the PL centre has different reaction on influence of an exciting light impulse. Each of the PL centres has a different constant of attenuation of radiation. So, if we shall measuring the intensity of the PL signals in the different moments of PL attenuation, we received the PL spectra that is resolved in time and their structure has more complex character, than at use of a continuous exciting light signal. The small duration of an impulse of an exciting light and its low power allows cutting the PL centres that have longer transition time in radiating state. The registration of the PL intensity in the different moments of time of attenuation allows to make a decomposition of the PL centres on time of attenuation of afterglow. It is necessary to note, that the informative element that is describing the individual PL bands in this case can be both the maximums, and the minimums of the dependencies that are presented on fig. 1.figFig. 1.
