组合材料芯片技术是功能材料开发研究的全新方法,能够高效、快速地筛选/优化新材料。采用这一技术快速发现/优化新型铝酸钆系发光材料(Gdl-xAlyOz∶Rex),并通过柠檬酸硝酸盐燃烧法制备的相同粉体的实验结果,考察了材料芯片筛选结果的可靠性。对发光体在波长为254nm的紫外光激发下进行实验,获得如下的研究结果:铝酸钆基体晶相中n(Gd)∶n(Al)的最佳比值为l∶1和3∶5。GdAlO3中的最佳激活剂(主要是Eu,Pr和Ce)为Eu,且Gdl-xA1O3∶Eux的主发射峰位置为615nm和593nm。Gdl-xA1O3∶Eux中的最佳掺量x值为0.09。
Composites Chip technology is a completely new approach to the development of functional materials that screens / optimizes new materials efficiently and quickly. The Gdl-xAlyOz: Rex, a new gadolinium-based luminescent material, was rapidly discovered / optimized by this technique. The reliability of the screening results of the material chips was investigated by the experimental results of the same powders prepared by the citrate nitrate combustion method. Experiments were carried out on the luminophore under the excitation of ultraviolet light with a wavelength of 254 nm. The results of the study are as follows: The optimal ratio of n (Gd): n (Al) in the gadolinium aluminate matrix phase is 1: 1 and 3: 5. The best activators (mainly Eu, Pr and Ce) in GdAlO3 are Eu, and the main emission peak positions of Gdl-xAlO3: Eu are 615nm and 593nm. Gdl-xA1O3: Eux in the best dosage x value of 0.09.
