This study aimed to fabricate transparent glass–ceramic coatings with luminescent characteristics. To this end, a SrO–AlO–SiO glass–ceramic system doped with Pr and Dy ions, referred to as luminescent glass–ceramic (LGC), was synthesized via melting at 1550 °C for 1 h. LGCs were added as mill additives to the transparent glass–ceramic coating recipe at increasing weight percentages of 5, 10, 20, and 40% (5Pr, 10Pr, 20Pr, and 40Pr, respectively). The coating specimens fabricated through the wet spraying technique were vitrified and recrystallized at 820 °C for 4 min, resulting in an LGC coating. Further, the chemical composition, phase structure, thermal behavior, and bonding characteristics of the LGC systems were analyzed, and spectrofluorometer and scanning electron microscope (SEM) analyses were performed after the coating procedure. The SEM indicated an increase in particle intensity per unit surface area. The spectrofluorometric analysis revealed that the standard sample did not display any discernible peaks; however, samples supplemented with particles exhibit emission bands at wavelengths of 485 (F → H, blue) and 575 nm (F9/2 → H, yellow) for Dy ions and at 485 nm (P→H, blue) for Pr ions. According to the CIE color graph, an increase in the quantity of added particles resulted in the region shifting toward the green–white area from the center of the blue–green region in the standard sample.

探索透明玻璃陶瓷涂层的发光：Pr3+/Dy3+共掺杂SrO–Al2O3–SiO2玻璃陶瓷颗粒的研究

本研究旨在制造具有发光特性的透明微晶玻璃涂层。为此，通过在1550℃下熔化1小时合成了掺杂Pr和Dy离子的SrO-Al2O-SiO玻璃陶瓷体系，称为发光玻璃陶瓷（LGC）。 LGC 作为研磨添加剂添加到透明微晶玻璃涂层配方中，重量百分比逐渐增加为 5%、10%、20% 和 40%（分别为 5Pr、10Pr、20Pr 和 40Pr）。通过湿喷涂技术制造的涂层样品在 820°C 下玻璃化并重结晶 4 分钟，形成 LGC 涂层。此外，还分析了 LGC 系统的化学成分、相结构、热行为和粘合特性，并在涂覆过程后进行了荧光分光计和扫描电子显微镜 (SEM) 分析。 SEM 表明每单位表面积的颗粒强度增加。荧光分光光度分析显示标准样品没有显示任何可辨别的峰；然而，添加了颗粒的样品在 Dy 离子的波长为 485（F → H，蓝色）和 575 nm（F9/2 → H，黄色）处显示出发射带，而 Pr 离子则在 485 nm（P→H，蓝色）处显示出发射带。根据 CIE 颜色图，添加颗粒数量的增加导致标准样品中的区域从蓝绿色区域的中心向绿白色区域移动。
