Laser-driven near-infrared two-region emission fluorescent ceramic as well as preparation method and application thereof
The invention discloses laser-driven near-infrared two-region emission fluorescent ceramic as well as a preparation method and application thereof, and relates to the technical field of fluorescent materials. According to the laser-driven near-infrared second-region emission fluorescent ceramic, MgO serves as a ceramic matrix, Ni < 2 + > and Cr < 3 + > ions serve as a light-emitting center, the emission peak range of the near-infrared second-region emission fluorescent ceramic is 600-1650 nm, two main peaks are located at 808 nm and 1330 nm respectively, the highest near-infrared second-region light output power reaches 214.00 mW under driving of 450 nm blue laser, and the laser-driven near-infrared second-region emission fluorescent ceramic can be used for preparing the near-infrared second-region emission fluorescent ceramic. The fluorescent powder shows an excellent imaging effect in penetrability test application, also has high thermal conductivity and thermal stability, and still keeps relatively high integral fluorescence intensity at a high temperature of 200 DEG C.
