AB  - A new method for the calculation of parameters is proposed. The method is based on determination of the glow curve maximum and effective values of the half-width and part of the half-width on the higher temperature side. A relation between the symmetry factor as a function of the corresponding constant alpha = n(0)(h + n(0)) and the correction factor Delta is obtained. An approximate symmetry factor function is derived, which enables analytical calculation of the parameters: activation energy E, constant alpha, and pre-exponential factor s ((h)). An iterative procedure is developed for more precise calculation of these parameters. The new method is checked for some characteristic values of the parameters. The connection between the models of general and mixed-order kinetics has been described theoretically.

AB  - Nickel and nickel-zinc ferrites are ones of the most abundant members of the soft magnetic materials. In the last few years, the interest in new methods of their preparation increases, because it is well known that the physical and chemical properties of these materials strongly depend on the preparing conditions. Powder samples of soft ferrites of NiFe2O4 and NixZn1-xFC2O4 were synthesized by a classical sintering procedure, planetary mill synthesis, and by a chemical procedure from complex compounds with acetylacetonato-ligands. Average particle sizes were 1 mum, 40 nm and 20x20x4 nm (slabs), respectively. All of the obtained materials were measured ill the frequency range of 7 - 12 GHz for the real and the imaginary part of permittivity and permeability, and the absorption coefficients were calculated. A concurrent analysis of the obtained values showed the influence of the method of synthesis, as well as the particle size on the absorption coefficients in the applied frequency range.

AB  - 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 determination 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.

AB  - A new glow curve fitting method using the Gauss-Lorentz asymmetric function is suggested. By calculating the thermoluminescence (TL) parameters it is shown that this is compatible with a general-order kinetics model. The relations between TL parameters and fitting function parameters are determined. The new fitting method is tested by computer simulated glow curves. The coefficients of Chens interpolation-extrapolation formula for calculation of TL parameters are presented in an analytical form. It is shown that the Chen method is a special case of the integral method of TL parameter calculation.

A new method for calculation of parameters is proposed. The method is based on the determination of the glow curve maximum, and the effective values of half-width and part of the half-width on the higher temperature side. The relation for the symmetry factor as a function of the corresponding order of kinetics I and the correction factor Delta is obtained.
