Abstract

The invention discloses a perovskite light-emitting device, a preparation method thereof and a display. The perovskite light-emitting device comprises a first injection layer, a first transmission layer, a light-emitting layer, a second transmission layer and a second injection layer which are sequentially stacked. The first injection layer comprises indium tin oxide. The second injection layer comprises carbon nanotubes. The light-emitting layer comprises halide perovskite, and light emitted by the light-emitting layer is emitted from the first injection layer and the second injection layer at the same time. The perovskite light-emitting device can stably emit light from two sides.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a perovskite light-emitting device, a preparation method thereof, and a display. Background technique [0002] Light-emitting diodes are currently the most popular materials and technologies in the field of light-emitting and display. With the advancement of science and technology, transparent display technology has become the development trend of future display, so there is a higher demand for performance parameters such as color purity, brightness, and luminous efficiency of light-emitting diodes. [0003] Organic light-emitting diodes (OLEDs) are the most mentioned in the current transparent display technology category. The transparent display technology based on organic light-emitting diodes has developed rapidly and has become a research hotspot. However, organic light-emitting diodes use organic materials, so the color purity is not high, and their pure colors r...
