Description

The preparation method of bluish voilet, green Si-Al-Zn system long-perisistance luminescent material
Technical field: the preparation method who the invention belongs to bluish voilet, green Si-Al-Zn system long-perisistance luminescent material.
Background technology: long-afterglow material is a kind of novel energy and material and energy-saving material.Utilize storage light-characteristics of luminescence it can be widely applied to all respects of production and people's lives.Long after glow luminous material mainly contains three big purposes at present: low emergency lighting, cue mark and decoration etc., this class material can be made luminous paint, light-emitting film, luminous fire protection safety sign, luminous printing ink, luminescent ceramic, luminescent plastics, luminescent fibre, luminescent paper, fluorescent glass etc., in building decoration, communications and transportation, military field important purposes is arranged all.
" Applied Physics wall bulletin " (Applied Physics Letter) rolled up 1715 to 1717 pages of the 12nd phases in 1999 75, delivered the article that is entitled as " adulterated ca aluminosilicate of trivalent cerium and yttrium-calcium aluminate crystalline are long-persistence luminous ", introduced two kinds of chemical formulas in the literary composition and be respectively Ca 2Al 2SiO 7And CaYAl 3O 7Crystal, trivalent cerium concentration is 0.05at.%.Synthesis condition is at first with the CaCO of stoichiometric ratio 3(4N), CeO 2(4N), Y 2O 3(5N), Al 2O 3(5N), SiO 2(5N) mixed grinding then, is in the iridium crucible of 46mm at diameter, and temperature is 1790-1850K, and pull rate is a growing crystal under the 0.5-2.0mm/h.Excite down Ca at the 365nm ultraviolet lamp 2Al 2SiO 7: the main emission peak of Ce is 417nm, and CaYAl 3O 7: the main emission peak of Ce is 425nm, remove excitaton source after, corresponding crystalline twilight sunset color is a bluish voilet, more than the sustainable 1h of its twilight sunset.
Summary of the invention: the preparation method who the purpose of this invention is to provide bluish voilet, green Si-Al-Zn system long-perisistance luminescent material.This method is selected raw material ZnO, SiO 2, Al 2O 3, activator Mn 2+Auxiliary activator M is La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, Bi, Ag, As, Al, Ga, Tl, Sb, Zr, Ti, Cr, Pb or Sn, has obtained a kind of new and effective long after glow luminous material by high temperature solid-state method.
The generation of steady persistence phenomenon be it is generally acknowledged owing to mix and is caused the generation of impurity level (defect level), in excitation phase, impurity level is caught hole or electronics, when excite finish after, these electronics and hole slowly discharge owing to thermal motion, energy is emitted in electronics and hole combination, thereby produces the steady persistence phenomenon.Trap can be in order to store electrons and hole, and when trap depth was too dark, electronics and hole can not discharge from trap, and when trap depth was too shallow, the d/d speed in electronics and hole was then too fast, and both of these case all is unfavorable for the generation of steady persistence phenomenon.Except requiring suitable trap depth, to have suitable avidity also very important electronics and hole in the adulterated ion pair trap, too by force or too weak avidity twilight sunset is not all had the prolongation effect.
It is ZnO: SiO that the present invention selects the matrix mol ratio 2: Al 2O 3=14～72: 14～72: 14～72mol%, activator Mn 2+Mol ratio is 0.005～5mol% of matrix, auxiliary activator M is La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, Bi, Ag, As, Al, Ga, Tl, Sb, Zr, Ti, Cr, Pb or Sn, mol ratio is 0.005～5mol% of matrix, under the air conditions, 800～1300 ℃ of pre-burning 1～6h, 1200～1550 ℃ of sintering 1～10h, lower the temperature product.Material aZnObAl of the present invention 2O 3CSiO 2: mM twilight sunset color is a bluish voilet, and main peak is positioned at 420nm, aZnbAl 2O 3CSiO 2: nMn 2+The twilight sunset color is green, and main peak is positioned at 520nm.
Preparation method of the present invention is simple, and the long-afterglow material twilight sunset color and luster that makes is various, and twilight sunset is bright, and time of persistence is long, excite 15min with the 254nm ultraviolet lamp after, in the dark, aZnObAl 2O 3CSiO 2: the naked eyes of mPr reach more than the 10h aZnObAl visible time of persistence 2O 3CSiO 2: nMn 2+Naked eyes reach more than the 15h visible time of persistence; Simultaneously, this long-afterglow material is "dead", can not work the mischief to environment.
