| titleOfInvention | A deep blue quasi-two-dimensional perovskite light-emitting diode |
| abstract | The invention belongs to the technical field of optoelectronic devices, and discloses a deep blue quasi-two-dimensional perovskite light emitting diode. The deep blue light emitting layer of the deep blue perovskite light emitting diode includes perovskite and doped alkali metal halide, large group organic halide and bisamine group organic halide. In the present invention, the high n-value phase in the quasi-two-dimensional perovskite is transformed into small-sized nanocrystals through the bisamine group organic halide, and the band gap width of the quasi-two-dimensional perovskite is increased, thereby enabling the perovskite to achieve spectral stability deep blue light emission. The generation of 2D phase (n=1) in perovskite is reduced by alkali metal halide, the non-radiative energy loss caused by strong exciton-phonon coupling in perovskite 2D phase (n=1) is suppressed, and the The synergistic effect with the bisamine group organic halide reduces the nanocrystal size in the quasi-2D perovskite, thereby further increasing the band gap width of the quasi-2D perovskite and further blue-shifting the luminescence of the device. |
