Under ultraviolet excitation, the material can emit blue light, and has a long-afterglow luminescent property. The material has potential to be applied as a novel illumination and display material.
Description
Technical field
The gallic acid zinc blue long afterflow luminescent powder that the present invention relates to a kind of doping bismuth of burst of ultraviolel, belongs to demonstration, sterilization and lighting fluorescent powder technical field.
Background technology
Long after glow luminous material has the light of holding, energy storage and the characteristic such as energy-conservation, in transform light energy with aspect utilizing, there is unique advantage, luminous energy can be stored, and then the energy of storage, the form with visible ray discharges lentamente, therefore, long after glow luminous material has unique application advantage in fields such as low light level illumination, emergent indications.For example: when the U.S.'s September 11 attacks that shock the world occur, the luminous sign that long after glow luminous material is made and indication mechanism play an important role in evacuating personnel process.Therefore the long after glow luminous material that, can realize in recent years " energy storage " and " energy-conservation " under natural light is one of focus of the subject researchs such as material, physics, the energy and chemistry.The emission band of long-afterglow material is from blueness to near-infrared band mainly.Wherein the luminosity of blue and green long afterglow material and time of persistence etc., luminescent properties reached the needs of practical application, and had realized suitability for industrialized production.Yet the long-afterglow material that sulfide, aluminate is matrix of take in the market easily absorbs airborne moisture, and deliquescence causes its afterglow property to reduce, and has limited its practical application.
Gallic acid Zinc material has near infrared and red long-afterglow material at present under the doping of rare earth ion, in the gallic acid zinc of the preparation progress > > document description doped with Mn of the < < gallic acid zinc doping manganese luminescent material of Shi Qiang, Wang Li, observe the green emitting that comes from Mn, but do not obtained coming from the green long afterglow transmitting of Mn.Blue long-afterglow material has important using value in fields such as emergent indication and illuminations, yet compare with the green gallic acid zinc luminescent material of mixing Mn with the gallic acid zinc near infrared long-afterglow material having developed at present, also lack the gallic acid zinc blue long afterflow material that excellent performance, thermostability and chemical stability are good.
Summary of the invention
For problems such as existing blue long afterflow material emission band narrow range on prior art market, kind are few, the invention provides a kind of gallic acid zinc blue long afterflow luminescent powder of doping bismuth of burst of ultraviolel, the present invention is achieved through the following technical solutions.
The gallic acid zinc blue long afterflow luminescent powder of doping bismuth, the expression formula of described this blue long afterflow luminescent powder is ZnGa
