A kind of inorganic energy storage ceramic luminous material and preparation method thereof

Abstract

The invention provides an inorganic energy-storage ceramic luminous material and a preparation method thereof: the inorganic energy-storage ceramic luminous material is composed of 50-90 parts of glass powder and 10-50 The total weight of the glass powder and the luminescent material is 100 parts; the glass powder is selected from glass powder with a melting point of 400-800°C; the luminescent material is a rare earth luminescent material. The inorganic energy-storing ceramic luminous material of the present invention can realize self-luminescence after having good light-absorbing energy storage and heat-absorbing energy storage, and can absorb heat above 38° in the external environment for energy storage and self-luminescence.

Description

technical field [0001] The invention belongs to the technical field of luminescent materials, and in particular relates to an inorganic energy storage ceramic luminous material and a preparation method thereof. Background technique [0002] At present, the self-luminous materials on the market use glass with a melting point of over 1000°C as the raw material. Since the maximum temperature that the general light-emitting materials can endure does not exceed 900°C, when the above-mentioned glass and the light-emitting materials are used together as raw materials to prepare the self-luminous materials, Since the melting point of the glass is higher than the tolerance temperature of the luminescent material, the luminescent performance of the luminescent material is bound to be destroyed, the luminous brightness of the self-luminescent material is reduced, and the user's requirements for luminous brightness cannot be met. [0003] In addition, the self-luminous material in the p...

Problems solved by technology

[0002] At present, the self-luminous materials on the market use glass with a melting point above 1000°C as the raw material. Since the maximum temperature that the general luminescent materials can withstand does not exceed 900°C, when the above-mentioned glass and luminescent materials are used as raw materials to prepare self-luminous materials, Since the melting point of glass is higher than the tolerance temperature of the luminescent material, it will inevitably destroy the luminous performance of the luminescent material, reduce the luminous brightness of the self-luminous material, and cannot meet the user's requirements for luminous brightness.

[0003] Moreover, the self-luminous materials in the prior art basically absorb light to store energy and then emit light. For places with poor lighting, the self-luminous material cannot absorb more light energy, and its ability to continue to emit light is affected. Its application scenarios relatively simple
