A combinatorial chemistry method was used to synthesize and screen (Y_xLu_1−x−y)₃Al₅O₁₂:Ce_3y green-yellow phosphors. The material libraries were obtained using an inkjet delivery system and screened for their fluorescence under an ultraviolet light of 365 nm. The optimized composition was identified to be (Y_0.2Lu_0.788)₃Al₅O₁₂:Ce³⁺_0.036. Scale-up experiments confirmed that the optimized composition of the phosphor showed the highest luminescence intensity and an excellent scintillation performance with a short decay time (<60 ns). The results indicated that the (Y_xLu_1−x−y)₃Al₅O₁₂:Ce_3y could be potentially useful as green-yellow phosphors for ceramic scintillators.
