Optical properties of Zn(II) complex using 1,2-bis(8-hydroxyquinolin-2-yl)ethane

Optical properties of Zn(II) complex using 1,2-bis(8-hydoxyquinolin-2-yl)ethane (Zn(BQOEH)), such as optical absorption, photoluminescence, and electroluminescence, are studied. Zn complex film emits a yellow photoluminescence band centered at 564 nm and an electroluminescence band at 567 nm. Transient characteristic of the organic light-emitting devices (OLEDs) with Zn(BQOEH) as the emitting material are demonstrated. An optical pulse of more than 5 MHz is obtained from the OLED with Zn(BQOEH).
