0736241OsinskiThis ARI project is aimed at development of novel rare-earth halide scintillating nanocrystals (NCs). A Colloidal synthesis approach will be used to prepare the NCs in reverse-micelle nanoreactors. To prevent deleterious effects of water vapor on the NCs, all handling of chemicals and reaction products will be performed in an Ar-filled glovebox with 0.1 ppm levels of H2O and O2. The reaction itself will also be carried out in Ar atmosphere. To protect hygroscopic cores, higher-bandgap water-resistant shells will be grown. The strong supportive infrastructure existing at UNM will be utilized, emphasizing institutional commitment to recruitment and retention of underrepresented groups. Students supported by the existing NSF-funded programs, such as the GK-12 on Graduate Teaching Fellows in K-12 Optics and Photonics Education and by the IGERT on Integrative Nanoscience and Microsystems at UNM will be given opportunity to work on the project.

0736241 Osinski ARI的这个项目旨在开发新型稀土卤化物纳米晶体（NC）。胶体合成方法将用于在反胶束纳米反应器中制备NC。为防止水蒸气对NC的有害影响，化学品和反应产物的所有处理均将在充氩手套箱中进行，H2O和O2水平为0.1 ppm。反应本身也将在Ar气氛中进行。为了保护吸湿性核心，将生长更高带隙的防水壳。将利用联合国墨西哥大学现有的强有力的支助性基础设施，强调对征聘和留住任职人数不足群体的机构承诺。由现有的NSF资助的项目，如GK-12在K-12光学和光子学教育研究生教学研究员和IGERT在UNM集成纳米科学和微系统支持的学生将有机会在该项目上工作。
