Single-layer polymer light-emitting diodes that employ different derivatives of Chromeno[3,4-b]quinoline as a guest doped in poly(vinylcarbazole )(PVK) with 2- tert-butylphenyl-5-biphenyl-1,3,4-oxadiazol (PBD) is reported. Energy transfer from the polymer blends, PVK with PBD(host), to Chromeno [3,4-b] quinoline derivatives(guest) is studied. In addition, the optical and electrical characteristics of materials and devices are investigated for optimization of device performance.
