Abstract

The invention near-infrared luminescence tellurium quantum dot doped red glass. The tellurium quantum dot doped red glass is prepared from, by mole, 0-25% of MgO, 0-25% of CaO, 0-25% of SrO, 0-25% of BaO, 0-35% of ZnO, 0-15% of Al2O3, 0.5-20% of TeO2, 0-5% of LiO2, 0-5% of Na2O, 0-5% of K2O and the balance P2O5. The invention further discloses a preparing method of the near-infrared luminescence tellurium quantum dot doped red glass. The glass is easy to prepare, does not need extra heat treatment, has a near-infrared broadband luminescence function and covers the range of 900-1500 nm. The glass is high in heat stability, is treated in a heat mode at the temperature of 500 DEG C-650 DEG C, does not fade and is expected to be applied to the fields of an optical fiber amplifier, a broadband tunable optical fiber laser device, an ultrashort pulse laser device and the like.

Description

technical field [0001] The invention relates to the technical field of red glass, in particular to a near-infrared luminescent tellurium quantum dot doped red glass and a preparation method thereof. Background technique [0002] Red glass is widely used in doors and windows, ceramic tile glaze, decorative finishing materials and handicrafts, including ruby ​​red glass, orange red glass containing cadmium sulfide, bright red glass containing cadmium selenide, brick red copper glass, glass containing sulfide Antimony cherry red glass, pink erbium-containing glass and other categories. Except for the erbium-containing glass which is derived from the absorption and coloring of erbium ions, other red glasses are basically derived from the coloring of semiconductor or metal colloids. After the mother glass is melted and shaped, these glasses need additional follow-up heat treatment to make these coloring groups aggregate and grow up. Depending on the size of the group, they will ...
