ABSTRACT The tris(8‐hydroxyquinoline)–aluminium complex is the most important and widely studied as electron transporting and green light emitting material. Alq3 and TbxAl(1‐x)q3 have been synthesized (where x = 0.1, 0.3, 0.5, 0.7 and 0.9) and blended films of Alq3 and TbxAl(1‐x)q3 with PMMA and PS at different percentage weight (wt%) concentrations (e.g., 0.1, 1, 5, 10, 25 and 50 wt%) have been prepared. The synthesized materials and their blended thin films have been characterized by a photoluminescence (PL) technique; the synthesis and PL characterization are reported in this paper. The synthesized metal complex shows bright emission of green light with blue light excitation (440 nm) and the prepared TbxAl(1‐x)q3 phosphor may be applicable in blue chip‐excited OLEDs for the newly developed wallpaper lighting technology.
