Abstract

The invention discloses an axiolitic Zn8[(BO3)3O2(OH)3]: Eu3<+> light emitting material with vortexes and a preparation method of the axiolitic Zn8[(BO3)3O2(OH)3]: Eu3<+> light emitting material. The nanosheet self-assembled axiolitic Zn8[(BO3)3O2(OH)3]: Eu3<+> light emitting material with vortexes is obtained through a hydrothermal synthesis reaction by taking zinc nitrate or zinc acetate, zinc acetate and ammonium borate as raw materials. The light emitting material disclosed by the invention is simple in method, low in cost and free of any additives. The obtained axiolitic Zn8[(BO3)3O2(OH)3]: Eu3<+> light emitting material with vortexes is good in monodispersity, uniform in shape and high in purity, has a good light emitting performance and is suitable for industrial production.

Description

technical field [0001] The invention belongs to the technical field of inorganic fluorescent materials, in particular to an ellipsoidal Zn 8 [(BO 3 ) 3 o 2 (OH) 3 ]:Eu 3+ Luminescent material and its preparation method. Background technique [0002] Metal borates have a series of excellent physical and chemical properties, and have attracted extensive attention from researchers, and borates with different shapes and sizes have an important impact on their properties. Hydrated zinc borate has been used as a flame retardant additive as early as 1940, when 2ZnO·3B was used 2 o 3 ·3H 2 O and 2ZnO·3B 2 o 3 ·7H 2 O Two hydrated zinc borates. With more than seventy years of development, zinc borate has been widely studied and applied in other fields such as flame retardants, lubricants, preservatives, fluorescent theme materials, and more and more hydrated zinc borates have been reported, such as 4ZnO·B 2 o 3 ·H 2 O, ZnO·B 2 o 3 1.12H 2 O, 2ZnO 2.2B 2 o 3 ·3H 2...
