Description

A kind of blue long afterflow fluorescent powder and preparation method thereof

Technical field

The invention belongs to phosphor technologies fields, more particularly to a kind of blue long afterflow fluorescent powder and preparation method thereof.

Background technique

Long-afterglow material is that one kind remains to after external stimulus (UV-visible light, X-ray, β ray etc.) stopping In considerable time (several seconds to ten more than hour) emit phosphorescence afterglow material long afterglow phenomenon before thousand in It is found in traditional Chinese Painting, and the scientific description in relation to long afterglow phenomenon can trace back to the 17th century still earliest, until 20th century, Science Report in relation to long afterglow is seldom always, and main cause has two o'clock, first is that long-persistence luminous intensity is lower, at that time weak Optical detector technology is difficult the very low twilight sunset of detected intensity；Second is that the afterglow intensity of long-afterglow material at that time is not high, Practical significance The landmark report of less related long-afterglow material research is derived from the text that Matszuzawa is delivered in August, 1996 Chapter, they have found, by long-afterglow material SrAl₂O₄: Eu²⁺In be co-doped with Dy³⁺, afterglow intensity can greatly enhance same with this When, it has also been found that codope Co can greatly improve afterglow intensity from this in ZnS:Cu, long-afterglow material is ground Takasaki etc. Study carefully and enters a new stage currently, long-afterglow material has been widely used in passive night mark and various has shown In track device

Currently, being concentrated mainly on blue-green luminous material for the research of long after glow luminous material, research system is mainly wrapped Include sulfide, aluminate and silicate etc..Early stage to sulfide systems is the study found that rare earth ion Dy³⁺And Tm³⁺Activation Sulfide can issue blue light.The long-afterglow material of aluminate-base plastidome largely shines in blue green light region, wherein preferably Blue long afterflow luminescent material be CaAl₂O₄: Eu²⁺, Nd³⁺, a length of 446nm of luminous spectrum spike, persistence can reach 1000min.In addition, using silicate as in the long after glow luminous material of matrix, related 2MOMgO2SiO₂: Eu, Dy(M Alkali earth metal) research it is the most extensive, by the control to matrix components and Doped ions concentration, light emitting region can To cover green-yellow light from blue violet light.Wherein, that the long-afterglow material better performances of blue light-emitting is Sr₂MgSi₂O₇: Eu²⁺, Dy^{3 +}, emit main peak and be located at 469nm, persistence can be more than 10h, and luminescent properties are better than CaAl₂O₄: Eu²⁺, Nd^{3 +}, and Sr₂MgSi₂O₇: Eu²⁺, Dy³⁺With good chemical stability and thermal stability, high-purity silicon dioxide raw material valence It is honest and clean to be easy to get, therefore always by the attention of people.
