specific Embodiment approach 1

[0004] Specific embodiment one: it consists of carbonate 35%-45%, silicate 5%-10%, halide 15%-25%, nanoscale powder metal oxide 25%-35%, nitrate 2%- 4% and 5%-7% of nanoscale powder rare earth elements, each component is weight percentage. The material of the present invention is made through the following steps: (1) accounting for 35%-45% of the total weight of carbonate, accounting for 5%-10% of the total weight of silicate and accounting for 25%-35% of the total weight % of nano-scale powdered metal oxides are fully mixed and added with water to make a rice paste; (2) add 5%-10% of the total weight of silicate; (3) stir the above mixture evenly; (4) add nano-scale Stir the powdered rare earth elements evenly; (5) add 2%-4% of nitrate in total weight and stir evenly; (6) use microwave to dry; (7) pulverize with a ball mill to obtain the material.

specific Embodiment approach 2

[0005] Specific embodiment two: the difference between this embodiment and embodiment one is that the carbonate is calcium carbonate, potassium carbonate, sodium carbonate or sodium bicarbonate. Halides are fluorite, halite or potassium halite.

Abstract

A luminescent material for electro-optical sources, involving a luminescent material containing nanoscale metal oxides for electro-optical sources, comprising 35-45 wt.% of carbonates, 5-10 wt.% of silicates, 15-25 wt.% of halides, 25-35 wt.% of nanoscle metal oxide powders, 2-4 wt.% of nitrates and 5-7 wt.% of nanoscale rare-earth elements. Since the material in this invention is a compound and doped material, the luminescence property of the material is largely altered. Due to the tunneling effect, electrons can realize transition between the interfaces of the insulating layer and the luminescent layer. When the electrons stop transition at the interface of the insulating layer and the luminescent layer, polarization occurs, and the polarized electric field is superimposed with the applied electric field to strengthen the electric intensity of the luminescent layer. The luminescent material in this invention has such advantages as high brightness, high optical efficiency, good coloration, low energy consumption, good adaptability, high response speed and long service life.

Description

Technical field: [0001] The invention relates to a luminescent material for an electric light source using a nanoscale metal oxide. Background technique: [0002] At present, the main lighting sources used in the market can be roughly divided into three types: incandescent lamps, fluorescent lamps, and gas discharge lamps. Among them, incandescent lamps also radiate infrared rays while radiating visible light, and a large part of electric energy is converted into heat, and the luminous efficiency is very low. Gas discharge lamps emit light by gas discharge, which comes from the radiation of gas atoms, and the spectral range is relatively narrow, so the color rendering is poor. A third common type of electric light source is the fluorescent lamp. Because it is an inductive load, the reactive power loss is relatively large, and waste lamps cause mercury pollution. Installation and maintenance are also inconvenient. Therefore, people in the industry have been studying solut...
