Abstract	Nanosize films of organic electroluminophors have offered the challenge to a new generation of light emitting devices - OLED. Tris-(8-oxyquinoline) aluminum $(Alq_{3})$ was one of the first compounds which demonstrated high efficient green electroluminescence and to the moment it is still used as emission and electron transport material in OLED. $Alq_{3}$ is known to exist in several polymorphs with photoluminescence (PL) maximum varied from 537 to 481 nm. One of main problem of OLED technology consists in a high cost of organic materials. An attempt to use organic-inorganic hybrid materials for a creation of a novel thin film emission device has not been very successful yet. But the investigation of hybrid material (HM) based on $B_{2}O_{3}$ glass matrix and $Alq_{3}$ as phosphor agent showed that there were observed a significant shift of luminescent peak to short waves after bulk HM annealing. The change in the luminescence spectrum can was explained by the polymorph and/or conformation transitions in $Alq_{3}$ in the crystal field of the matrix.
