Description
Technical field
The present invention relates to a kind of fluorescent material that can be used for preparing LED light and applications, belong to physics photoelectric field.
Background technique
With the continuous development of society, the corresponding technology such as electronic equipment, device is also constantly updating, white hair
Optical diode (white LEDs) is widely popularized in fields such as illumination, FPD, light decorations.But now for
The research of white light LEDs is still current one of emphasis, because current commercial white light LEDs product is mainly swashed with blue-ray LED
Yellow fluorescent powder YAG:Ce is sent out to form white light, this combination leads to the colour rendering index of light source due to lacking red spectral components
Lower, colour temperature is higher, it is difficult to meet the application demand of high performance device.Then, with commercial red fluorescence powder Y2O3:Eu3+'s
Occur, this phenomenon is improved, but the red fluorescence powder cannot effectively absorb within the scope of near ultraviolet, greatly weakens
Luminous brightness, therefore its application still allows of no optimist.Also, existing fluorescent powder preparation process is complicated, and yield rate is not
Height limits its normal use.
Summary of the invention
In view of the above-mentioned problems of the prior art, can be used for preparing the glimmering of LED light the object of the present invention is to provide a kind of
Luminescent material and application, material property is stablized, and its luminance purity is good, brightness is high, good luminescence property.
To achieve the above object, the technical solution adopted by the present invention is that: a kind of fluorescent material can be used for preparing LED light,
Chemical formula is Na2-2xEu2xMo2O9, wherein x is trivalent europium ion Eu3+The mole percent of doping, 0.001≤x < 1.0.
As a preferred embodiment, x=0.2-0.3.
The present invention also provides the applications of the above-mentioned fluorescent material that can be used for preparing LED light, and fluorescent material is cooperated and is coated
In LED light luminescent element surface, white light can be issued.
Compared with the existing technology, the present invention has the advantage that
(1) raw material that uses of the present invention is easy to get, and operating procedure is simple, favorable repeatability；
(2) fluorescent material that the present invention is prepared can launch feux rouges, and sample crystallinity is preferable, function admirable；Hair
Optical purity is good, brightness is high, can be applied to prepare light-emitting component.
