Abstract
The present invention is the spontaneous aura material of a kind of redness and preparation method and application.Its composition mainly is in the alkaline earth sulfide as matrix, mixes two kinds of rare earth ion europiums (Eu) and thulium (Tm).Then certain ratio blended mixture is placed in the alumina crucible through grinding, and is heated to 1000～1200 ℃ through 0.5～2 hour postcooling promptly in inert atmosphere.Sneak into as in vectorial fluid behind the red spontaneous aura material porphyrize that obtains, adopt the way of coating, sintering or cast that it is lodged on various required substrates, just can obtain to use widely.The spontaneous aura material of redness of the present invention need not be special irradiation, only under the normal temperature ordinary light, in the dark promptly can be observed twinkler, luminous intensity is strong, and longer duration.
Description
The present invention is a kind of red long afterglow luminous material, and preparation method thereof and in many-sided application.
Not following 1,100 kinds of the luminescent materials of having found up to now, but all need excitaton source, they can be divided into according to the characteristics of mode of excitation: photoluminescence (photolumi nescence) material, electroluminescent (electroluminescence) material, cathode radioluminescence (cathodoluminescence) material, thermoluminescence (thermolum inescence) material and optical excitation luminous (optically stimulated lu minescence) material etc. for example: at United States Patent (USP) U.S.4,314, the CaS:Eu that is reported in 037, CaS:Eu:Ce, CaS:Eu:Ce:Na and (Ca, Sr) S:Eu, (Ca, Sr): Eu:Ce, (Ca, Sr) S:Eu:Ce:Na etc. is exactly a cathode radioluminescence material used in trichromoscope, it must use under electron-beam excitation, and definitely can not produce aura under normal temperature and natural light.
How some long persistence phosphor uses as long persistence oscilloscope and various steady persistence picture tube, but all needs special light source and power drives.
Mixing the II-VI compounds of group of rare earth impurities mostly uses in cathode radioluminescence and electroluminescent, some is quite a few as the embedded photoluminescent material of fundamental research, for example in Applied Physics 56 volume 2 phases (1987) 176-185 and J.Chem.Phys.Vol.30 No.2(1959) work done among the 434-441 and enumerate singly mix europium and singly mix the sulfurated lime or the strontium sulfide of thulium, when with light source when their effective excitation wavelength excites, can detect luminous with detector, but luminous intensity is low, life-span is short, be generally nanosecond (ns) to millisecond (ms) magnitude, as remove light source, move on to that the dark place is luminous just not to have been had.Even this class luminescent material has steady persistence also to occur as a kind of background, because very weak can not the application.
In the anti-false way of trade mark and coin, often use luminescent material at present, but must utilize special light source (for example utilizing ultraviolet lamp procuratorial work counterfeit money and some trade mark etc.) during check, because client does not possess detection means, often be taken in. and do not need excitaton source and detector, as long as shading can present bright luminousing image a little, make everybody can debate the true and false and false proof, this just people to seek.
Main purpose of the present invention provide a kind of can be under the normal temperature ordinary light luminescent material of spontaneous red-emitting; Chemical ingredients and the preparation method and its application of this material are provided.Can utilize material of the present invention to manufacture anti-false trademark, the various signs that are used for anti-vacation, and utilize material of the present invention to manufacture the decoration fine arts goods that certain views and admires light fixture and recreation place.
This material of the present invention does not need special excitation, just can launch very strong ruddiness under ordinary light, and without sensitive detection parts, as long as it is moved to the dark place, by visual observation, visible the sustainable 2-5 of aura minute, therefore be called " red spontaneous aura material ".
The main matrix composition of material of the present invention is an alkaline earth sulfide, and before not adding other composition, it does not have any available optical characteristics.And when mixing into europium and thulium ion, it becomes efficient aura body.Its luminous mechanism is different with common photoluminescence and thermoluminescence, but be the symphyogenetic result of light and heat. when under indoor spuious visible light effect, the electronics of europium ion is excited, again under the heat effect of room temperature, from this ion-transfer to another ion, then again under same room temperature heat effect, electronics shifts from the second ion thulium, be accompanied by this process, launch the red light (see figure 1), and the luminous time length very longly can reach 3-5 minute (see figure 2) usually.
One, the Chemical Composition of luminescent material of the present invention
The main component of material of the present invention is an alkaline earth sulfide, wherein is mixed with two kinds of rare earth ion europiums (Eu) and thulium (Tm), adds an amount of alkaline earth fluoride and vitriol simultaneously, increases luminous intensity.Rare earth ion can be an oxide compound, or sulfide or the adding of halid form.The ratio of its molecular weight is:
M(Ca,Sr)S 100 mol%
M(Ca,Sr)F
