Abstract
A fine-granularity light-accumulating fluorescent powder of alkali-earth metal aluminate features use of Eu as main activating agent, and has the chemical formula: (A1-x-yDxEy)O.a(G1-zHz)2O3, where A is at least one of alkali-earth metals including Mg, Ca, Sr and Ba and di-valente metal Zn, D is Eu as activating agent, E is co-activating agent, the rare-earth element may be Dy, Nd, Pr, Ho, Er, Tm, Yb, or Lu, the transition element may be Mn, Zr, Nb, Ti, Sb, Li, Ge, In, or W, G is matrix co-crystal Al, H is matrix co-crystal B or Ga, x=(0.0001-0.5), y=(0.0001-0.3), z=(0.0001-0.5) and a=(0.5-3.0).
Description
The present invention relates to fine granule luminous storage fluorescence powder and preparation method thereof.
Luminous storage fluorescence powder be a kind of after the sun or other light source irradiation, have hold optical property, in the dark can send for a long time residual light, can repeatedly repeat to hold light and luminous again material.Luminous storage fluorescence powder mostly was sulfide-based compound, for example Z in the past
nS:Cu, C
oOr C
aS:C
eDeng, though this class luminous storage fluorescence powder can absorb ambient light, in the dark launch residual light then, but has only 1～2 hour to tens hours between the residual light time, and the weak chemical stability of sulfide-based compound has determined them not water-fast, easily aging, experience just decline fast of brightness after tens hours, work-ing life is short.The another kind of luminous storage fluorescence powder of exploitation in the past contains radioactive substance, can be luminous voluntarily in for a long time, but radioactive substance is the dangerous source of pollution of generally acknowledging, and to human body, all can produce severe impairment to environment, so forbidden in the world to use.
Through long term studies, having occurred for the first time with the alkali earth metal aluminate in the early 1990s is the luminous storage fluorescence powder of matrix.This class is by E
uThe luminosity height of activated aluminate luminous storage fluorescence powder, can reach more than 24 hours between the residual light time, and excellent in stability, moisture-proof, anti-exposure in sunshine, life-span is long, thereby obtained application in every field, for example with luminescent ink, luminescent coating, luminous plastics, noctilucence glass printing, be coated with and make various indications or decorative kind product and all promoted widely at aspects such as low-light (level) light sources.
But this class aluminate luminous storage fluorescence powder is with α-Al at present mostly on industrial-scale production
2O
3After the compound of several necessary components, undertaken by the high temperature solid state reaction more than 1300 ℃, in this case, the final product that obtains is the scleroma piece of ceramic-like often, and this is because α-Al
2O
3Chemically reactive very low, only under sufficiently high temperature, could interact with the compound of other component such as alkaline-earth metal, generate the monoclinic form aluminate, and make rare-earth activated dose as E
U2O
3Deng entering lattice, form luminescence center and electronics deep trap.Must apply powerful processing such as pulverizing ball milling for hard like this product strictly according to the facts, just can reach tens microns powder of actual requirement.But must make light-emitting crystal structures be subjected to a certain degree destruction like this, produce many defectives.These defectives can absorb and excite luminous energy and few luminous.Continue to be crushed to below the 10 μ m, brightness just sharply descends, residual light is decay fast also, continue carefully below 3 μ m again, the luminous practicality that has lost it that it is faint, this just makes them in special dimension such as intaglio printing, the luminescent ink of offset printing, duplicate the noctilucence powdered carbon, the application of industries such as silks and satins fabric printing pigment is restricted.In order to improve the thick and wide drawback that distributes of particle size, a lot of researchs in the past all do not obtain fine solution.
On the other hand, the aluminate luminous storage fluorescence powder is to rely on E at a low price
uIon is as main activator.As everyone knows, E
uBe the ion that appraises at the current rate, wherein+2 and+3 valence states during as the fluorescent material activator, send far different spectral response curve, alkali earth metal aluminate has only+divalent just can produce deep trap in being with, and in the preparation, normally uses+E of 3 valencys
U2O
3As E

u 2+, solid state reaction must be carried out in reducing atmosphere.Self-evident, can be E

2(5%) mobile N
2In realize E
uReduction.This method must be carried out in tight tube furnace, inconvenient operation not only, and increased cost of equipment, be difficult to form scale production again.
The objective of the invention is to avoid above-mentioned weak point of the prior art and provide a kind of do not reduce luminosity and between the residual light time and good fine granule luminous storage fluorescence powder and the manufacture method thereof of water tolerance.
Purpose of the present invention can reach by following measure:
