| titleOfInvention | Fluoride nanometer crystal for wideband optical amplification and preparation method and application of fluoride nanometer crystal |
| abstract | The invention relates to a fluoride nanometer crystal for wideband optical amplification and a preparation method and application of the fluoride nanometer crystal in the technical field of materials science. According to the fluoride nanometer crystal for the wideband optical amplification, NaYF4: Yb, Re@NaYF4 or NaGdF4: Yb, Re@NaGdF4 nanometer crystal is in a monodisperse nucleocapsid structure. Laser of 980nm is used for exciting the monodisperse nanocrystal, and multi-band near infrared luminescence is produced; the peak position of a luminous peak is freely mixed with the fluoride nanometer crystals at different wave bands, so that the near infrared luminescence using a rare earth ion as a luminescence center is formed, and the effective bandwidth is enlarged. For the nanometer crystal in the monodisperse nucleocapsid structure with the near infrared luminescence is in a hexagonal phase structure, the luminescence center is free from the influence of high energy groups, the lower conversion luminescence efficiency and the luminous intensity are effectively improved, and the fluoride nanometer crystal is extremely suitable for the wideband optical amplification. |
