Problems solved by technology

However, due to the serious triplet-triplet annihilation and poor carrier transport ability of the currently reported phosphorescent complexes, the complexes often need to be in a very low and narrow doping concentration range to achieve high High-performance electroluminescence, which requires relatively harsh device preparation conditions, resulting in higher costs in industrial production and affecting product quality and commercial competitiveness

Abstract

Belonging to the technical field of semiconductor materials, the invention in particular relates to an organic metal iridium complex and application thereof. When the organic metal iridium complex isused as a luminescent layer doping material of OLED devices, the manufactured OLED devices have good photoelectric performance, the driving voltage of the devices can be significantly reduced, and atthe same time the current efficiency, external quantum efficiency and lifetime of the devices are all greatly improved, thus meeting the requirements of panel manufacturing enterprises.

Description

technical field [0001] The invention belongs to the technical field of semiconductor materials, and in particular relates to an organometallic iridium complex and an application thereof. Background technique [0002] Organic electroluminescence (OLED: Organic Light Emission Diodes) device technology can be used to manufacture new display products and also can be used to make new lighting products, which is expected to replace the existing liquid crystal display and fluorescent lighting, and has a wide application prospect. [0003] Currently, OLED display technology has been applied in smart phones, tablet computers and other fields, and will further expand to large-size applications such as TVs. However, compared with the actual product application requirements, the luminous efficiency and service life of OLED devices need to be further improved. [0004] The OLED light-emitting device is like a sandwich structure, including electrode material film layers, and organic func...
