A new method for analysis of the glow curve with one maximum is described. This method is based on fitting the experimental glow curve with a new type of asymmetric Gauss-Lorentz (GL) function. This function was adapted to be very precise in describing glow curves. A completely new algorithm for calculating the kinetic parameters of the process for the OTOR (One Trap-One Recombination center) model or the model of ideal phosphor was developed. The kinetics order concept was used for calculation of the kinetic parameters of the process. The kinetics order parameter was defined by means of real physical parameters. A new function was proposed to describe the dependence of the factor symmetry of order kinetics. It has enabled a very accurate calculation of the activation energy parameter. The resulting relative error was less than 0.5%.
