摘要
α-Gd2(MoO4)3 晶体是采用共沉淀法制备前驱体，在 800 °C 下烧结合成的。得到的 α-Gd2(MoO4)3 呈单晶结构，X 射线衍射信号中有一个强主峰（-221）。为了开发发光材料，在合成过程中需要加入稀土离子。通过掺杂 Tb3+ 和 Eu3+，Gd2(MoO4)3 下转换荧光粉在紫外 LED 芯片、防伪货币和指纹识别方面显示出了应用潜力。此外，将[Er3+]/[Yb3+]和[Ho3+]/[Yb3+]离子共掺杂应用于 980 纳米 LED 芯片时，可产生绿色和红色发射，可用于防伪油墨。利用钆的磁性来确认磁共振成像发光。此外，还开发了一种用于热探测的柔性复合材料，并探索了它的各种应用。
Various Applications of Gadolinium Molybdate Down-Conversion and Up-Conversion Fluorescent Nanoparticles
Crystalline α-Gd2(MoO4)3 is synthesized by sintering at 800 °C using a coprecipitation method to prepare the precursor. The resulting α-Gd2(MoO4)3 displayed a monocrystalline structure with a strong main peak (-221) in the X-ray diffraction signal. To develop a light-emitting material, rare earth ions are added during synthesis. By doping with Tb3+ and Eu3+, the Gd2(MoO4)3 down-conversion phosphor shows potential for use in UV–LED chips, counterfeit money prevention, and fingerprint identification. Additionally, co-doping with [Er3+]/[Yb3+] and [Ho3+]/[Yb3+] ions produce green and red emissions when applied to a 980 nm LED chip, useful for anti-counterfeit ink. The magnetic properties of gadolinium are leveraged to confirm magnetic resonance imaging luminescence. A flexible composite for heat detection and explored various applications for its use is also developed.
