Organic luminophor metal complex in inorganic glass matrix—A new hybrid material

• Hybrid materials of B2O3 glass matrix and organic phosphors (Alq3, Gaq3, and Inq3) were melt made.
• Melt synthesis time increase results in a shift of HM׳s luminescence from green to blue.
• Luminescence lifetimes of Meq3 based HMs were fitted by two exponents.

Hybrid materials were synthesized on the base of borate glass matrix and the tris(8-hydroxyquinoline) aluminum, gallium and indium (Mq3=Alq3, Gaq3, and Inq3) organic complexes, which are used as phosphors in OLED devices. The luminescence properties of hybrid materials containing 0.02–0.1 wt% of Mq3 in B2O3 glass matrix were studied. It was found that the luminescence peaks of hybrid materials were significantly shifted to shorter wavelengths. The measured luminescence lifetimes of Mq3 based hybrid materials fitted by two exponents were found to be several times less for the shorter components and nearly the same for the long components when compared with pure Mq3.
