The temperature influence and the structure changes of polymer matrix on fluorescence of impurity luminescence centers were investigated. The obtained data broadens the perspectives of using triphenylmethane dye as a detector that helps to analyse physical conditions of polymers. Computer simulation of polymer matrices structuring process was carried out. The results of the calculations by the methods of MM+ and ZINDO/S prove the mechanism of appearance of hysteresis as a change of environing geometry of luminescent centers.
Исследовано влияние температуры и изменения структуры полимерной матрицы на флуоресценцию примесных центров свечения. Полученные данные открывают перспективы применения трифенилметановых красителей в качестве датчиков, позволяющих анализировать физические состояния полимеров. Проведено компьютерное моделирование процессов структурирования полимерных матриц. Результаты расчетов методами ММ+ и ZINDO/S подтверждают механизм появления гистерезиса как изменение геометрии окружения центров свечения.
