Abstract
effect of temperature on the spectrum and amplitude of luminescence of the MDMO-PPV polymer embedded in a porous silicon (pSi) microcavity (MC) was studied. The contribution of different mechanisms to temperature-induced shift of MC eigenmode was examined. It was shown that heating of pSi MC can be used to clean its surface from nonspecific molecular contaminants, while cooling allows drastic reduce the response time of MDMO-PPV luminescence to TNT vapors.
