Dendritic Mesoporous Silica Structuring of Eu3+-Doped Ca2SiO4 Nanophosphors for Bioimaging and Luminescent Applications来源 ：ACS PublicationsRare-earth element-based nanophosphors are known for their exceptional optical properties, rendering them useful for applications in bioimaging and light-emitting diodes (LED). However, traditional phosphors often suffer from drawbacks such as photobleaching in organic dyes and toxicity of quantum dots. In this study, we address these challenges by employing dendritic mesoporous silica nanoparticles (DMSNs) as host materials for fabricating Eu3+-doped calci...

Solar-Driven Cr(VI) Detoxification via a Holmium-Modulated In2S3 Strategy A Rare-Earth Approach to Sustainable Photocatalysis 来源：ACS PublicationsThe photocatalytic reduction of hexavalent chromium Cr(VI) under visible light has gained considerable attention due to its relevance to environmental remediation. In this study, Ho-doped In2S3 photocatalysts were synthesized via a photodeposition method to improve the Cr(VI) reduction performance. The characterizations of the synthesized catalysts were performed using various techniques, including X-ray diffraction, scanning electron microscopy, tran...

来源：ACS PublicationsRare-earth metal and actinide based thin films are promising materials for applications ranging from optoelectronics to energy storage and conversion. While chemical vapor deposition (CVD) exhibits substantial advantages over physical vapor deposition, CVD processes rely on precursor design to achieve a high volatility, appropriate stability, and controllable reactivity. This is particularly challenging for rare-earth metals and actinides since they primarily form ionic bonds. Despite the challenges, the number of rare-earth metal and actinide CVD precursors has greatly incr...

来源：ACS PublicationsOpen-shell nanographenes have attracted significant attention due to their structurally tunable spin ground state. While most characterization has been conducted on weakly interacting substrates such as noble metals, the influence of magnetic surfaces remains largely unexplored. In this study, we investigate how TbAu2, a rare-earth-element-based surface alloy, affects the magnetic properties of phenalenyl (or [2]triangulene (2T)), the smallest spin-1/2 nanographene. Scanning tunneling spectroscopy (STS) measurements reveal a striking contrast: while 2T on Au(111) exhibits a ...
