Anti-stokes fluorescence of phenalemine 512 dye in polymeric matrix at low-intensity excitation

Anti-Stokes fluorescence of phenalemine 512 dye (Ph512) in polymeric matrix was detected at low-intensity excitation by He-Ne laser, laser diode and luminodiode. Temperature dependences of anti-Stokes fluorescence Ph512 in polymeric matrix were obtained. Temperature dependence of scattering radiation of excitation source was found.
