Organic luminophor metal complex in inorganic glass matrix-A new hybrid material
Hybrid materials were synthesized on the base of borate glass matrix and the tris(8-hydroxyquinoline) aluminum, gallium and indium (Mq(3)=Alq(3), Gaq(3), and huh) organic complexes, which are used as phosphors in OLED devices. The luminescence properties of hybrid materials containing 0.02-01 wt% of Mq(3) 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 Mq(3) 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.
