摘要（英）：

The invention discloses near-infrared luminescence transparent glass ceramic. A composition general formula of the near-infrared luminescence transparent glass ceramic is aSiO2-bAl2O3-cCaO-dNa2O-eIn2O3-xEr2O3, wherein a, b, c, d, e and x are molar fractions, and the data ranges are respectively as follows: a is greater than or equal to 40 and is less than or equal to 65, b is greater than or equal to 10 and is less than or equal to 25, c is greater than or equal to 7 and is less than or equal to 15, d is greater than or equal to 12 and is less than or equal to 25, e is greater than or equal to 1 and is less than or equal to 15, x is greater than or equal to 0.01 and is less than or equal to 2, and a+b+c+d+e+x=100. The near-infrared luminescence transparent glass ceramic disclosed by the invention is prepared through a melt quenching method, and an obtained material has the characteristic of near-infrared emission under bandwidth ultraviolet excitation.
