An optimal number of the thermoluminescent methods for the estimation and control of the characteristic parameters of electron traps in a photosynthetic structure (the activation energy Etm and the electron-trapping frequency νtm) has been determined. They include the method of determining the energy Etm by matching the calculated and experimental spectra, direct methods for calculating the parameters Etm and νtm using the initial rise of the thermoluminescence intensity in the [log I,103/T] coordinates, the diagram of the characteristic parameters Etm and νtm of the traps, which is universal for a wide variety of phosphors and pho-toconductors, and the dependence of the energy Etm on the temperature of radiation maximum. The parameters Etm and νtm are calculated and the kinetic properties of the traps Z, ZV, А(S3Qa), Q(S2Qа), B1(S3Qb), В2(S2Qb), and С are analyzed. |

Определено оптимальное число термолюминесцентных методов для оценки и управления характеристическими параметрами электронных ловушек в фотосинтетической структуре (энергия активации Etm и частота захвата электронов νtm). К их числу относится метод определения энергии Etm путем сопоставления расчетного и экспериментального спектров, прямые методы расчета параметров Etm и νtm с использованием начального повышения интенсивности термолюминесценции в координатах [log I,103/T], диаграмма характерных параметров Etm и νtm ловушек, которая является универсальной для широкого спектра люминофоров и фотопроводников, а также зависимость энергии Etm от температуры максимума излучения. Рассчитаны параметры Etm и νtm и проанализированы кинетические свойства ловушек Z, ZV, А(S3Qa), Q(S2Qа), B1(S3Qb), В2(S2Qb) и С. |
