Problems solved by technology

The production of calcium phosphate zinc thallium phosphor and powder coating and use on the inner wall of the lamp tube are relatively dangerous, which poses great hidden dangers to the environment and people. Moreover, the light decay of this kind of phosphor is relatively large, and the life of the lamp tube emits medium-wave ultraviolet rays. shortened, so neither phosphor is ideal

Embodiment 1

[0010] Embodiment 1: take calcium carbonate (CaCO 3 ) 3.5g, magnesium oxide (MgO) 0.4g, boric acid (H 3 BO 3 )21.6g, diamine hydrogen phosphate [(NH 4 ) 2 HPO 4 ]6.6g, lead oxide (PbO) 0.1g, dilanthanum trioxide (La 2 o 3 ) 0.81g, the above-mentioned raw materials were crushed separately to make the particle size <7μ, and then fully mixed, put it into an alumina crucible, put it into a box furnace and slowly raise the temperature to 900 ° C, keep the temperature for 2 hours, take out the crucible and cool it to room temperature, and then The material in the crucible is finely passed through a 200-mesh sieve, put into the crucible again and burned at 950°C for 1 hour, crushed to 320 mesh, and the finished product is obtained after sieving. The spectrum measured by the fluorescent powder ultraviolet analyzer is a band spectrum, and the peak value is λ=2850 Ȧ.

Embodiment 2

[0011] Embodiment 2: take by weighing strontium carbonate (SrCO 3 ) 10.35g, magnesium oxide (MgO) 0.4g, boric acid (H 3 BO 3 )21.6g, diamine hydrogen phosphate [(NH 4 ) 2 HPO 4 ]6.6g, lead oxide (PbO) 0.1g, dilanthanum trioxide (La 2 o 3 ) 0.81g, the preparation process is with example 1. The spectrum of this embodiment is still a band spectrum, but the spectrum is shifted to the long wave, the peak value is λ=2970 Ȧ, and the intensity is stronger than that of phosphate activated by calcium zinc thallium and gadolinium.

Embodiment 3

[0012] Embodiment 3: the dilanthanum trioxide (La 2 o 3 ) into an equivalent amount of samarium trioxide (Sm 2 o 3 ) or gadolinium trioxide (Gd 2 o 3 ), other raw materials and preparation process are with embodiment 1.

Abstract

A health-care fluorescent-lamp powder can prevent osteoporosis. It is a kind of alkali boron phosphate with expression formula ((Mo)1-3. (B203)1-4. (P205)0.1-1:Pb0.005-1. Y0.01-1), M belongs to one or above of calcium, magnesium, strontium and sulfone, and Y is one or above of rare-earth ion lanthanum, samarium and gadolinium. The process is carried out by mixing one or above of calcium carbonate, strontium carbonate and barium carbonate with one or above of magnesium oxide, boric acid, ammonium dibasic phosphate, lead oxide, lanthanum oxide, gadolinium oxide and samarium sesquioxide and solid-phase firing at high-temperature. It can transmit medium-wave ultraviolet with peak value=2970, convert human-body hypodermic 7-deoxycholesterol into vitaminD3, and improve human-body calcium-phosphorus metabolism. It can be used for health-care fluorescent-lamp in family and hospital.

Description

Technical field: [0001] The invention belongs to the technical field of lighting, and in particular relates to a fluorescent fluorescent powder capable of radiating a specific wavelength with a health care function. technical background: [0002] It is well known that 7-dehydrocholesterol in the human body can be converted into vitamin D under the irradiation of medium-wave ultraviolet rays. 3 , promote calcium and phosphorus metabolism in the human body, and calcify bone matrix. In the prior art, general lighting fluorescent lamps (fluorescent lamps) have no fluorescent powder that can emit medium-wave ultraviolet rays in the tube wall, and the tube wall coating of fluorescent lamp tubes for health care purposes already has calcium zinc thallium phosphate (Ca 0.94 Zn 0.06 ) 3 TL 0.03 (PO 4 ) 2 (Chinese Patent No. 96116266.x), or gadolinium-activated phosphate (Ca.12n.Gd) 3 (PO 4 ) 2.14 (Chinese Patent No. 022465014), used to emit medium-wave ultraviolet rays.
