Spectroscopic analysis of Pr3+:CaYAlO4 crystal

Eu3+/2+ co-doping system induced by adjusting Al/Y ratio in Eu doped CaYAlO4: preparation, bond energy, site preference and 5D0–7F4 transition intensity

“…But, the stronger emission of 5 D 0 – 7 F 4 disappeared when Eu 3+ and Tb 3+ were co-doped into CaYAlO 4 . 29 However, in our work, the relative intensity of 5 D 0 – 7 F 4 and 5 D 0 – 7 F 2 can be modified by changing the Al 3+ and Y 3+ ions ratios in CaY 1− x Al 1+ x O 4 and the Judd–Ofelt theory 30 was applied to calculate the radiative properties of the prepared materials.…”

Single-Phase Organic–Inorganic Hybrid Nanoparticles for Warm-White Lighting

“…This may be attributed to the fact that the 3 P 0 → 3 H 5 as the green light channel has the largest emission crosssection. 31 The results indicate that the organic−inorganic hybrid materials have strong crystallinity, minimal surface imperfections, and good luminescence donor and acceptor composites.…”

Nanowire Genome: A Magic Toolbox for 1D Nanostructures

“…[268] Interestingly, when the length of Ag NWs was increased to 20 µm, only some segments of the NWs were converted into hollow structures (Figure 12k) due to the hydrolysis of Pd 2+ before the reaction completed. [260,269,270] In addition, by introducing a reductant (such as ascorbic acid), Ag NWs were controllably modified with a small amount of Pd (5 at%), leading to excellent chemical stability against oxidation. [271] In addition to the noble metal alloy nanostructures, Ag NWs can also transform into 2G semiconductors or silver halide nanomaterials.…”
