| 简介 |
Material that generates white light from ultraviolet radiation. The present invention provides a transparent nano-ceramic material doped with three rare earth ions (ce3 -tb3 -eu3) based on kyf nanocrystals4 dispersed in a sio matrix2, leaving the rare earth ions incorporated in these nanocrystals. Taking advantage of the low phonic energies of the nanocrystalline environments, which minimize non-radiative energy losses and through efficient processes of absorption, emission and transfer of energy between the rare earth ions, white light emission is generated as a result of the addition of the three primary colors.
