The invention discloses a self-crystallizing all-inorganic perovskite quantum dot glass with high luminous intensity and a preparation method thereof. The glass is prepared from the following raw materials in mole percentage by a one-step melting and quenching method: B 2 O 3 25-30%, SiO 2 23～29%, ZnO 4～8%, SrO 1～2%, Cs 2 CO 3 5～7%, PbX 2 3～4%, NaX 3～4%, Li + 17～36%, wherein X is Br or I; the high luminous intensity self-crystallized all-inorganic perovskite quantum dot glass of the present invention has excellent luminous intensity, and shows bright green light or red light under the excitation of 365nm ultraviolet light, which is better than the all-inorganic calcium obtained by traditional annealing and crystallization. The luminous intensity of the titanite quantum dot glass is increased by 1-2 times, and the water-photothermal stability of the luminescence is also very good, and the preparation method is simple. , cost saving, suitable for industrial production and market promotion and application. |
