| titleOfInvention | Mixed multi-cation perovskite material film with optical gain characteristic and preparation method and application thereof |
| abstract | The invention discloses a mixed multi-cation perovskite material film with optical gain characteristic, and a preparation method and application thereof, wherein the general chemical structure formula of the mixed multi-cation perovskite material film is [ (A) 0.87 BxCy)PbX 3 ] b [A’ 2 PbX 4 ] c ；A 0.87 In BxCy, x + y is 0.13, 0.87 is the mass ratio of a to the total mass of a + B + C, x is the mass ratio of B to the total mass of a + B + C, and y is the mass ratio of C to the total mass of a + B + C; the thickness of the mixed multi-cation perovskite material film is 20 nm-200 nm; the gain coefficient is 800-3000cm ‑1 (ii) a The light-emitting wavelength range is 510-530 nm; the roughness is 0.5nm-5 nm. The invention improves the optical and thermal stability of the perovskite material and the gain characteristic of the thin film. |
