Although DCM molecules are widely used in the field of lasers, organic light-emitting diodes, and etc., there are relatively few studies on its luminescence properties in solid matrices. In this paper DCM with 1% and 5%weight ratios were dissolved in poly(methyl methacrylate)(PMMA), and its emission process were analyzed at different temperatures. It was found that DCM sample(1% weight ratios)matrix polarity did not show significant change in temperature range of 295-35 K.However, DCM samples of 5%weight ratios, showed reduced matrix polarity in the temperature range of 295-195 K. Both DCM samples show fluorescence intensity and fluorescence lifetime increases with temperature decrease.
