| 简介 | A family of quantum upconversion glass-ceramic nanocomposite pigments, useful for security and display applications are of particle-in-matrix construction. The embedded phase is a rare earth fluoride crystal, which is responsive for quantum upconversion, and is of nanometer size. The continuous or encapsulating phase is amorphous glass such as silica, to provide a barrier to the rare-earth fluoride crystals. The pigments are synthesized via a sol-gel process. | ||
