An approximation of phosphorescence decay kinetics of ideal phosphors by a general order kinetics model
Abstract
The phosphorescence of ideal phosphors has been investigated using a general order kinetics model. The regions where the model describes the phosphorescence processes exactly and approximately have been identified. In order to characterize these processes. the mean value of the kinetics order has been defined for the part of the curve of immediate interest. It has been shown that the value of the order of kinetics for ideal phosphors in the transition region cannot have a unique physical interpretation. The general order kinetics model enables theoretical explanation of some important physical characteristics of TL processes for the ideal phosphors. For the theoretical curves, obtained by the band model, the parameters of phosphorescence curves have been determined using the general order kinetics model. The results differ from the exact values by 3%. We conclude that the general order kinetics model enables a better understanding of the physical processes. and an approximate determina...tion of the phosphorescence decay parameters. This points out the theoretical and practical value of the model. (C) 2001 Elsevier Science B.V. All rights reserved.
