摘要

通过使用基于立体光刻技术的数字光处理（DLP）三维打印技术进行压制、后续烧结和无压烧结，获得了(Gd,Y)3Al2Ga3O12:Ce闪烁体的致密透明陶瓷样品。分析了化学计量偏差和绿色体压制方法（单轴压制与 DLP 三维打印）对陶瓷的光学、发光和闪烁特性的影响。成分中过量的 Y 和 Gd 会导致透射率增加和闪烁动力学加速。此外，还发现由三维打印绿色体制成的透明陶瓷在光产率方面优于由相同粉末制备并通过单轴压制致密的样品。

Scintillation and Luminescent Properties of the (Gd,Y)3Al2Ga3O12:Ce Ceramics Obtained by Compaction of Green Bodies Using Digital Light Processing 3D Printing

Dense and transparent ceramic samples of a (Gd,Y)3Al2Ga3O12:Ce scintillator were obtained by using stereolithography-based Digital Light Processing (DLP) 3D printing for compacting, subsequent burnout, and pressureless sintering. The effects of stoichiometric deviations and green body compaction methods (uniaxial pressing versus DLP 3D printing) on the optical, luminescent, and scintillation properties of ceramics were analyzed. An excess of Y and Gd in the composition led to an increase in transmittance and to the acceleration of the scintillation kinetics. Moreover, transparent ceramics made of 3D-printed green bodies were found to be superior in light yield to the samples, which were prepared from the same powders and densified by uniaxial pressing.

期刊介绍： Photonics (ISSN 2304-6732) aims at a fast turn around time for peer-reviewing manuscripts and producing accepted articles. The online-only and open access nature of the journal will allow for a speedy and wide circulation of your research as well as review articles. We aim at establishing Photonics as a leading venue for publishing high impact fundamental research but also applications of optics and photonics. The journal particularly welcomes both theoretical (simulation) and experimental research. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. There is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. Electronic files and software regarding the full details of the calculation and experimental procedure, if unable to be published in a normal way, can be deposited as supplementary material.
