US 2022/0302393 A1 · HALIDE MATERIAL AND OPTICAL UNIT AND OPTOELECTRONIC DEVICE HAVING THE SAME

Abstract

A halide material having general formula ArMAX is disclosed. The halide material can be processed to an optoelectronic film with a halogenated formamidine and a lead halide, and the optoelectronic film can be applied in the manufacture of an optoelectronic device like a perovskite laser or a PeLED. Experimental data have proved that, the fabricated optoelectronic film shows a property of photoluminescence (PL) peak wavelength adjustable. Moreover, the PL peak wavelength moves from 482 nm to 534 nm with the increase of the content of lead (Pb), halogen (X) and formamidine (FA) in the optoelectronic film Furthermore, experimental data have also indicated that, the fabricated optoelectronic film can be used as a blue emissive layer, a red emissive layer or a green emissive layer, thereby having a significant potential for application in optoelectronics industry.
