The present work reports the study of KCl thin films doped with In+ or Tl+. Both systems show optical absorption bands similar to single crystals. As the impurity concentration increases, so does the absorption as also the half band width, unlike in KCl: Cu+ films. Further experimental techniques such as X-ray diffraction, scanning electron micrographs and energy dispersive X-ray observations were used and comparative analysis with KCl : Cu+ films reveals new conditions for better crystallinity of the samples.
