A combinatorial chemistry method was employed to screen the yellow phosphors of (Lu₁₋(x)Gd(x))₃Al₅O₁₂:Ce₃(y) as luminescent materials. An array of 81 compositions was synthesized by inkjetting nitrate solutions into microreactor wells and sintering at high temperature. The candidate formulations were evaluated by luminescence pictures, and the optimal composition was determined to be Lu(2.7)Gd(0.3)Al(5)O(12):Ce(0.045) after scale-up and detailed characterization. Lu₂.₇Gd₀.₃Al₅O₁₂:Ce₀.₀₄₅ was also found to have a short decay time (≤53.97 ns). These results demonstrate the great potential of the Lu₂.₇Gd₀.₃Al₅O₁₂:Ce₀.₀₄₅ as a component of ceramic scintillators.
采用组合化学方法筛选（Lu₁₋(x)Gd(x))₃Al₅O₁₂:Ce₃(y) 黄色荧光粉作为发光材料。通过喷墨将硝酸盐溶液注入微反应器井中并在高温下烧结，合成了 81 种组成的阵列。通过发光照片评估候选配方，并通过放大和详细表征确定最佳组分为 Lu(2.7)Gd(0.3)Al(5)O(12):Ce(0.045)。还发现 Lu₂.₇Gd₀.₃Al₅O₁₂:Ce₀.₀₄₅ 的衰减时间较短（≤53.97 ns）。这些结果表明，Lu₂.₇Gd₀.₃Al₅O₁₂:Ce₀.₀₄₅ 作为陶瓷闪烁体的组成部分具有巨大的潜力。
