Abstract: Using red and infrared (IR) filters in various studies in the near IR region, in particular, studying photosensitized generation of singlet oxygen and photosensitizers triplet states, in many cases filters luminescence is not taken into account. The paper shows how standard absorbing glass filters affect the luminescence signal in the near IR region.

Keywords: filter luminescence, time-resolved spectroscopy, luminescence spectra.
