A type of oxadiazole-functionalized iridium complex is newly employed as red phosphor emitter in polymer lightemitting devices (PLEDs) using a blend of poly (9,
Improved performances are obtained in organic light-emitting diodes (OLEDs) based on the indium-tin oxide(ITO) anode processed with ultrasonic in Al2O3 polishin
We present the propagation of cylindrical waves in the media whose permittivity varies with time abruptly or continuously. By the method of variable separation,
Tunnelling of a two-level atom is investigated in the two-photon mazer when the atom is initially prepared in a coherent superposition state and the cavity in v
