Kyushu Univ: ‘Perovskite LED’ with 4x luminous efficiency: for next-generation displays
-Acceleration of next-generation display development-
Kyushu Univ / Kyoto Univ / Chinese Academy of Sciences / Sorbonne Univ
Research groups such as Kyushu University have succeeded in improving the luminous efficiency of quasi-two-dimensional perovskite LEDs by about 4 times.
Selection of suitable organic materials:
By selecting an appropriate organic material, a perovskite thin film can be easily produced and emits light with high color purity.
‘Perovskite LED’ is expected to be used for next-generation displays with low cost and high color purity.
In addition, if this method is used, the laser oscillation characteristics from perovskite can be expected to improve, contributing to the medical and communications fields.
