我们通过在 1550°C 下对 Cr3+ 掺杂的 SiO2-Al2O3-Y2O3 玻璃进行热处理，开发出含有红宝石晶体的玻璃陶瓷。玻璃基体中析出晶体的形状为棒状，其平均宽度和长度分别约为10和200μm。根据X射线衍射测定和电子探针X射线微量分析，确认棒状晶体为α-Al 2 O 3 。在 1300°C 以上热处理的玻璃陶瓷中观察到 694 nm 处的 Cr3+ 强发射带（称为 R 线）。此外，通过光致发光映射图像仅在α-Al2O3棒状晶体中观察到强烈的红色发光。
We have developed the glass ceramics containing ruby crystals by heat treatment of a Cr3+-doped SiO2–Al2O3–Y2O3 glass at 1550°C. The shape of precipitated crystals in the glass matrix was rod type whose average width and length were around 10 and 200 μm, respectively. From an X-ray diffraction measurement and an electron probe X-ray microanalysis, it was confirmed that the rod crystals were α-Al2O3. Intense emission bands of Cr3+ at 694 nm, called the R-lines, were observed in the glass ceramics heat treated above 1300°C. In addition, the intense red luminescence was observed only in the α-Al2O3 rod crystals by a photoluminescence mapping image.
