Color-control of the persistent luminescence of cadmium silicate doped with transition metals

Semi‐conductive, Switchable Dielectric and Photoluminescent Properties of Two High‐Temperature Phase Transition Hybrids

“…4 T 1g (G) transition of Mn 2 + . [34][35][36] It can be visually understood as the excitation from C (0.2477, 0.5450) to obtain D (0.6070, 0.3924) emission (Figure S5) [37,38] As the temperature decreases, the photoluminescence intensity 1 (Figure 5c) and 2 (Figure 5d) increases monotonically. It shows that the structure changes before and after the phase transition (383 K/380 K), which makes the fluorescence intensity significantly reduced, but there is no red shift or blue shift, which is similar to the results of previous studies.…”

“…Under the excitation condition of 486 nm, 1 has an emission band at 527 nm and showed green emission (Figure 5a), which can be as-cribed to the πS!n or πS!π electronic transitions. [31][32][33][34] It can be visually understood as the excitation from A (0.0899, 0.1564) to obtain B (0.0988, 0.7882) emission (Figure S5). [22] Under the excitation condition of 557 nm, 2 has an emission band at 595 nm and showed yellow emission (Figure 5b), which can be attributed to the 6 A 1g (S)!…”

Synthesis and luminescent properties of Tb3+ activated cadmium silicate nanophosphor

“…Over the last decade, the development of phosphors with diverse luminescent colors has proved to be of immense significance due to the variety of applications such as luminous ceramics, optoelectronic devices, display devices and radiation detectors [1][2][3]. Further, rare earth activated phosphors find huge advantages such as fast response time, high illumination and contrast ratio, light weight and low power consumption.…”

Long Persistent Phosphor CdSiO3:Gd3+,Bi3+ and Potential Photocatalytic Application of CdSiO3:Gd3+,Bi3+@TiO2 in Dark

“…Only one broad excitation band peaked at 243 nm can be observed and it is due to the host absorption of CdSiO 3 . The intense broad LPL emission band in range 360–700 nm (peaked at 448 nm) is attributed to a localized electron–hole pair, a self‐trapped excitation (STE), which is enhanced by the incorporation of RE 3+ ions occupying Cd 2+ sites . The nonequivalent substitution would create the positively charged [Bi cd • ], [Gd cd • ] defects as electron capture, and the negative [V cd ’] defects as hole capture.…”
