“…The thickness of these layers was measured by a Jobin Yivon UVISEL ellipsometer. TPD blending in PQP or PQM can improve the property of hole transportation; moreover, the blends decrease fluorescent quenching of PQP or PQM [11,12]. BCP was used as a hole-blocking layer [11,13] and deposited by vacuum evaporation onto spin-coated layers (devices III and IV ), and then AlQ 3 was deposited onto the BCP layer, served as an electron-injecting and transporting layer [3,14,15].…”

Two novel polymers PQP(poly(3, 7-N-octyl phenothiozinyl cyanoterephthalylidene)) and PQM (poly(3, 7-N-octyl phenothiozinyl cyanoisophthalylidene)) containing phenothiazine were synthesized for application in red and orange light-emitting diodes. The synthesized polymers were characterized using UV-visible, photoluminescence and electroluminescence (EL) spectroscopy. The single-layer EL devices of indium tin oxide(ITO)/PQP(or PQM)/Mg : Ag and multi-layer devices of ITO/PQP(or PQM): N, N′-diphenyl-N, N′-bis(3-methylphenyl) -[1, 1′-biphenyl]-4, 4′ -diamine(TPD) (44 nm)/2, 9-dimethyl-4, 7-diphenyl -1, 10-phenanthroline (BCP, 5 nm)/tris(8-hydroxyquinolinato) aluminium(AlQ3, 20 nm)/Mg : Ag were fabricated. The EL spectra from the devices based on PQP peaked at the wavelength of 664 nm and covered red and infrared regions. The maximal brightness was measured to be about 60 cd m−2 at the applied voltage of 17 V. The devices based on PQM gave bright orange light-emission peaking at 608 nm and the maximal luminance was 150 cd m−2 at the applied voltage of 14 V.

“…along with different ligands, like 2-(2-hydroxyphenylbenzoxazole), 8-hydroxyquinoline, 1,10-phenanthroline, 2,2'-bipyridine, etc. [5][6][7]. Nowadays cadmium complexes have been synthesized by different groups for their use in OLED applications due to their thermal stability, simplicity in synthesis procedure and wide spectral range.…”

A novel route was employed for the synthesis of pure and guest surfactant (CTAB) assisted cadmium[(2-(2-hydroxyphenyl)benzoxazole)-(8-hydoxyquinoline)] having composition Cd(HPB)q nanorods, where HPB = 2-(2-hydroxyphenylbenzoxazole) and q = 8-hydroxyquinoline. Powder X-ray diffraction analysis was used for structural analysis and to calculate the particle size using Scherrer equation. Fourier transform infrared spectroscopy was employed to confirm the composition of Cd(HPB)q. Scanning electron microscope images indicated that lower temperature and a shorter reaction time would be suitable for the formation of nanorods. UV-vis-NIR spectroscopy was used to determine the band gap energies of Cd(HPB)q complexes. Photoluminescence spectra showed a prominent peak around 500 nm, which indicated a strong photoluminescence emission in the green region making the complex a promising organic light emitting diode (OLED) candidate.

“…During the last decade, organic chemists have seen a great development in the preparation of hosts and emitters comparable to Alq 3 , and further improvements in the efficiency of OLEDs materials have been achieved [15][16][17][18][19][20]. By using various substitutions at Alq 3 and investigating its photophysical properties, one can provide an important approach to modify the photoluminescence and thermal properties of Alq 3 derivatives [20,21].…”
