Tris(8‐hydroxyquinoline)boron (Bq 3 ) was synthesized by means of a high‐temperature substitution reaction. Mixtures of different Bq 3 polymorphs were obtained and their spectral and structural properties were investigated. A comparison of organic light‐emitting diode (OLED) structures with Bq 3 and Alq 3 as emitting materials showed the prospective application of Bq 3 as a blue‐light emitter. Thin‐film hybrid materials (HM) were made by vacuum thermal deposition. HM films were produced by layer‐by‐layer thermal vacuum sputtering of B 2 O 3 /Alq 3 /B 2 O 3 /MoO 3 /Al on a glass substrate with an indium tin oxide (ITO) conducting layer. The HM films were locally heated by a diode laser (785 nm). The pumping of 150 W cm –2 energy for one second resulted in an irreversible change in the HM film. Chromaticity coordinates for the as‐prepared and laser‐induced HM films showed a significant difference in their photoluminescent properties.
