Abstract
The invention discloses a kind of environmentally protective medium wave ultraviolet fluorescence powder, the environmentally friendly medium wave ultraviolet fluorescence powder includes following mass percentage raw material: SrO 15%-35%, B2O340%‑60%、P2O50.8%‑2.5%、Gd2O30.2%‑0.5%、MgO 13%‑20%、La2O30.1%-0.5%.The high-intensitive medium wave ultraviolet with spectrum of 290-320nm can be issued under 254nm ultraviolet excitation using strontium tetraborate as the fluorescent powder of principal crystalline phase, and because of presence unleaded in formula, do not can cause environmental pollution in production and use process.And the introducing of lanthanum can reduce the excessively high caused quenching effect of gadolinium concentrations, to improve the luminous intensity of fluorescent powder.
Description
Technical field
The present invention relates to a kind of environmentally protective medium wave ultraviolet fluorescence powders, specially illuminating material technical field.
Background technique
Getting sun is the main method for preventing Rickets In Infants And Children.By the ultraviolet B radiation of optimal wavelength 290-320nm
Irradiation, under human epidermal 7-DHC can photochemical reaction switch to vitamin D3, can effectively adjust inside of human body calcium phosphorus generation
It thanks, achievees the effect that prevent and treat osteoporosis, Rickets In Infants And Children.Northern area winter Ultraviolet B (UV-B) is big
Gas-bearing formation absorbs, thus winter osteoporosis, Rickets In Infants And Children are high-incidence.Therefore by can irradiate ultraviolet B radiation have one
The fluorescent lamp for determining health-care effect becomes the effective ways of prevention and treatment rickets.
Currently, containing zinc, the phosphate matrix of thallium or gadolinium activated phosphate matrix fluorescent powder because launch wavelength range away from
Farther out or the intensity deficiency of spectral content medium wave part causes photochemical effect undesirable from best irradiation wavelengths, these still have spy
It is perfect.And although the best peak position of the fluorescent powder containing the rare earth-borons phosphate matrix such as lanthanum, gadolinium is preferable, intensity is not high and ingredient in
Contain heavy metal lead (patent No. CN2005100
19088.x).In leaded fluorescent powder, since lead is as heavy metal, phonon energy is lower, excites by outside energy
When be conducive to electronics in transition between the energy levels, so the luminous intensity of fluorescent powder can be improved.But leaded fluorescent powder is because poisonous and harmful
And pollution environment, it should generally be forbidden to use.
Summary of the invention
The purpose of the present invention is to provide one kind using alkaline-earth metal borophosphate as matrix, using gadolinium oxide as the nothing of activator
Lead health care fluorescent material.
To achieve the above object, the invention provides the following technical scheme: a kind of environmentally protective medium wave ultraviolet fluorescence powder includes
Following mass percentage raw material: SrO 15%-35%, B2O3 40%-60%、 P2O5 0.8%-2.5%、Gd2O3 0.2%-0.5
%、MgO 13%-20%、La2O3 0.1%-0.5%。
Further preferably, the environmentally protective medium wave ultraviolet fluorescence powder includes following mass percentage raw material: SrO
20% 、B2O3 60%、 P2O5 2%、Gd2O3 0.5%、MgO 17%、La2O3 0.5%。
Wherein SrO is introduced with carbonate form, B2O3It introduces as boric acid, P2O5It is introduced with biphosphate ammonium form,
He is introduced substance in the form of pure-oxide.
A kind of environmentally protective medium wave Ultraluminescence powder, preparation method thereof: environmentally protective medium wave ultraviolet fluorescence powder mass percentage
Drug is weighed, by SrO, B2O3、P2O5 、Gd2O3 、MgO、La2O3 Grinding after mixing evenly, is placed in 700 DEG C of -1100 DEG C of Elemas
Electric furnace high temperature calcination 2-3 hours takes out honed 350 mesh of crushing ball, as medium wave ultraviolet fluorescence powder finished product after cooling.
Compared with prior art, beneficial effects of the present invention are as follows: being the fluorescent powder of principal crystalline phase in 254nm using strontium tetraborate
The ultraviolet with spectrum of high-intensitive medium wave of 290-320nm can be issued under ultraviolet excitation, and because of presence unleaded in formula, is produced and made
With not can cause environmental pollution in the process.And the introducing of lanthanum can reduce the excessively high caused quenching effect of gadolinium concentrations, to mention
The luminous intensity of high fluorescent powder.
