Three polymorphs of tris(8-hydroxyquinoline)boron (Bq3) were obtained by high-temperature substitution reaction. Their spectral and structural properties were investigated and showed Bq3 to be a potential blue emitter. Hybrid material (HM) films B2O3/Alq3/B2O3 on a glass substrate were made by vacuum sputtering. Laser heating of the HM film resulted in an irreversible change in its photoluminescence.
