In the azo dye-doped polymer film, the time response of photoinduced anisotropy due to trans-cis photoisomerization is influenced by condition of polymer matrix and also depends on the environment such as laboratory temperature. For Methyl red (MR) doped Polymethyl methacrylate film, the temperature dependent time response of the photoinduced dichroism was measured, and the influence of the sample temperature on the trans - cis photoisomerization of MR was investigated.
