Abstract
A method is proposed for determining the accumulation time and concentration of triplet molecules in frozen solutions of organic compounds. This method is based on measuring the change in the intensity of phosphorescence for a given change in the intensity of photoexcitation. A comparison of the values of these quantities, determined by the known method on the ignition and attenuation kinetics of phosphorescence and the proposed method, is carried out. Their good agreement is shown and the advantages of this method are noted.
