Hybrid materials based on organic luminophores in inorganic glass matrix

Hybrid materials were synthesized based on borate glass matrix and the tris(8-hydroxyquinoline) aluminum (Alq 3 ) organic luminophore, which is used as a green luminophore in OLED devices. The luminescent properties of hybrid materials with 0.02–0.1 wt % of Alq 3 in glass were studied. The luminescence peak of the hybrid material is significantly shifted to shorter wavelengths (443 nm versus 518 nm in pure Alq 3 powder).
