Problems solved by technology

These products all have a common feature: in the same matrix, the luminescent centers of different elements are introduced, that is, the luminescent centers come from different raw materials, and the luminescent centers emit light separately. Such products often lead to non-radiative relaxation between the luminescent centers of different elements. Yu, so that the luminous efficiency is reduced, and the mixing and ratio control process of different raw materials is complicated

Abstract

The invention discloses Mn<2+> activated white light glass and a preparation method thereof. The chemical composition of the material is xZnO-(60-x)N2O3-40P2O5: yMn<2+>, wherein x is equal to 10-50 and y is equal to 0.1-5. The preparation method of the glass comprises the following steps: accurately weighing solid raw materials including ZnO, H3BO3, NH4H2PO4 and MnCO3; uniformly mixing according to a ratio; heating at 1100 DEG C-1300 DEG C for 0.5h-3h until the raw materials are fused; annealing; and cooling to a room temperature. The obtained product is stimulated by 350nm ultraviolet light, and an emission spectrum is composed of a blue light broad emission band at a 443nm site and an orange light broad emission band at a 574nm site; and color coordinates (x=0.3234 and y=0.3261) are located in an ideal white light region. The product does not contain rare earth, and the preparation method is simple and is suitable for industrial production.

Description

technical field [0001] The present invention relates to white light glass, in particular to a kind of Mn 2+ An activated white light glass material capable of covering all wavelengths and a preparation method thereof; specifically relates to a Mn glass material whose excitation wavelength is located in the violet region and whose emission wavelength is located in the blue, green, and orange regions. 2+ An activated white light glass material and a preparation method thereof; it belongs to the technical field of luminescent materials. Background technique [0002] White light for traditional lighting usually uses an ultraviolet light source to simultaneously excite red, green, and blue light materials, and the three primary color materials are matched in a certain proportion to obtain white light. For example, on the surface of the lampshade of the energy-saving lamp, the red light material Y is coated 2 o 3 :Eu 3+ , Green light material LaPO 4 :Ce, Tb and the blue light...
