Temperature dependent quantum cutting in cubic BaGdF 5 :Eu 3+ nanophosphors. This paper presents an overview of the recent results on upconversion andphotoluminescence of rare-earth ions in nanoenvironments. Top % 2: Indicates that the scientist is among the Top 2% Scientists in the specified subject among the scientists in the AD Scientific Index in the World and/or Country.

Subject field ranking in world, region, country and university is beta version since subject field 'others' (597.069 scientists profile whose branch cannot be determined, not yet edited or determined) is excluded, so the ranking will change as the others fields are edited. Quantum yields are found to be 75% and 42% for doped and core-shell samples, respectively.* According to Total H. Energy transfer efficiencies from Ce 3+ to Tb 3+are 65% and 45% for doped Na(Y 1.5Na 0.5)F 6:Ce:Tb material and NaYF 4: Ce/ Tb core-shell materials, respectively. However, Reddy, an Infosys employee in his mid-30s, and Ghosh, escaped safely. The decay times are found to be 8.4 ms and 5.4 ms for doped nanorods and core-shell nanoparticles, respectively, which reveals that non-radiative decay is higher in the case of core-shell nanoparticles than doped nanorods. Two Indian nationals Vishwakant Ankit Reddy and Pushpendu Ghosh were among the hostages involved when Monis began his siege. Cell volume, cell parameters and lattice strain have been modified due to core-shell structure. The hexagonal crystal phase of Ce 3+-doped sodium yttrium fluoride nanocrystals is converted to the cubic polymorph after surface coating by TbF 3. The core-shell nanoparticles are confirmed by X-ray diffraction study and transmission electron microscopy ( TEM) analysis. 43 405401 View the article online for updates and enhancements. prepared by modifying the previously reported methods (Ghosh and Mudring.
