چکیده انگلیسی
This study reports on the properties of organic light-emitting diodes (OLEDs) with zinc (II) [2-(2-hydroxyphenyl)benzoxazole] as a hole-blocking layer. OLEDs devices are prepared in a conventional OLEDs structure (i.e., anode/HTL/EL/HBL/cathode and anode/HTL/HBL/EL/cathode). The luminescence efficiencies and the turn-on voltage are significantly affected by the existence of the hole-blocking layer. This is attributed to an excellent hole-blocking property, which is in turn due to the high HOMO energy level (6.5Â eV). The device showed luminous efficiency 2.46Â lm/W at 5Â V. The maximum luminance of about 10,000Â cd/m2 is obtained, and the turn-on voltage (2.5Â V) is affected by the existence of the hole-blocking layer.
