Description
Technical field
The present invention relates to luminescent material technical fields, and in particular to a kind of preparation method of Bi doping borofluoride.
Background technique
Bismuth (Bi) element causes the electron configuration of bismuth ion to be easy to lose electricity since outer shell electronics is not completely filled
Therefore son there are the bismuth ion of a variety of valence states and is easily formed cluster in compound.Due to the exposed electricity of bismuth ion outermost layer
Sub- configuration, shining for bismuth ion is very sensitive to the variation of crystalline environment field around it, such as: when the dopant material for changing bismuth ion
Matrix, regulate and control field environment around bismuth ion, can make bismuth ion shine from ultraviolet light change to blue and green light even to
Yellow light forms the very wide fluorescence spectrum of transmitting range.
The bismuth ion of positive trivalent is most common and most stable of bismuth ion valence state in nature.The Bi in different substrates3+From
The fluorescent characteristic of son is by systematic research.In general, Bi3+The photon of Ions Absorption ultra-violet (UV) band, launches from 300nm to 650nm
Blue green light broad emission band.Bi3+The material of ion doping also has excellent performance in white light LEDs field, in white light LED fluorescent powder
In, Bi3+Ion is commonly used to absorb black light and transfer energy to shining in green wavelength.And bismuth is a kind of nontoxic
Harmless environment protection metal, referred to as " green bismuth ".Importantly, the cost of bismuth is low, it is unique nontoxic trivalent heavy metals ion,
Many fields have great attraction, and its property is similar in some aspects to rare earth ion, so if with bismuth from
Cost can not only be reduced when rare earth ion, in this way application in son substitution matrix but also can be reduced pollution to environment and
Harm to organism.
At present due to lack efficient stable blue-green fluorescent powder, LED shine there are colour renderings it is poor, colour temperature is high the problems such as.
Most popular blue-green fluorescent powder physicochemical property is unstable currently on the market, and not environmentally, preparation cost is high by preparation process, uses
The pollution of heavy metal or nitride to environment and the harm to organism.Although having been used for commercial object, show
It is not able to satisfy the demand of people so.
In pervious report, although there are much discussion about boric acid system, it is based on Sr5(BO3)3The fluorescent powder of F
Seldom it is discussed.There is presently no about based on Sr5(BO3)3The Bi of F3+The research report of doping fluorescent powder.
