Ultra-wide spectrum near-infrared fluorescent material and near-infrared fluorescent ceramic and preparation methods thereof, and device
The invention provides an ultra-wide spectrum near-infrared fluorescent material and near-infrared fluorescent ceramic and preparation methods thereof, and a device. The chemical composition of the ultra-wide spectrum near-infrared fluorescent material is (Sr[1-y]Ba[y])[3]Sc[4-x]Cr[x]O[9], wherein y is more than or equal to 0 and less than or equal to 1, and x is more than 0 and less than or equal to 0.5; under the excitation of blue light, the near-infrared fluorescent material can generate near-infrared light emission of which the emission wavelength ranges from 600 nm to 1500 nm, the main peak of an emission spectrum ranges from 830 nm to 900 nm, and the full width at half maximum of the emission spectrum is larger than 180 nm. Compared with the prior art, the ultra-wide spectrum near-infrared fluorescent material prepared by the preparation method has brand-new chemical composition and can be excited by blue light to emit near-infrared light, so that the luminescent material is applied to a near-infrared light source.
本发明提供了一种超宽光谱近红外荧光材料、近红外荧光陶瓷及制备方法和装置。所述超宽光谱近红外荧光材料的化学组成为(Sr1‑yBay)3Sc4‑xCrxO9，其中，0≤y≤1，0
