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.
Keywords: thermal hysteresis of the luminescence; triphenylmethane dyes; structural modification of the polymer.
