Structural and optical studies of cerium doped gadolinium oxide phosphor

Thermally stable and color-tunable bi-activated (Dy3+/Eu3+) alkaline earth metasilicate phosphor for luminescent devices

“…It can be ascertained that the crystalline size decreases as the concentration of co-dopant ions increases, which implies that the contraction in the lattice may occur via occupying the larger ionic radii site (Ca 2+ ) by smaller ionic radii (Dy 3+ & Eu 3+ ) ions. 25,26 3.1.2. Morphological analysis with FE-SEM.…”

Three-Dimensional Indium Iron Selenide Nanoarchitecture as an Efficient and Durable Electrocatalyst for the Hydrogen Evolution Reaction

“…However, the strength of these peaks diminished as the indium concentration increased (Figure b). The observed decrease in peak intensity can potentially be attributed to the disparity in electron densities between host and dopant materials, primarily contingent upon factors such as the scattering factor and structure factor . The decrease in the crystallite size, observed as the concentration of In 3+ increases, falls within the range of 26.1–27.8 nm, which is considerably smaller compared to the crystallite size of pristine FeSe 2 measuring 30.2 nm (Table S1 of the Supporting Information).…”

The effect of zinc and sodium borate doping on the structural, morphological, optical, electrical and electrochemical properties of PEDOT:PSS thin film electrodes for flexible and transparent supercapacitor applications

“…This result is evidence of successful doping. 34,35 FTIR spectroscopy was used to determine the nature of the interaction between NaB and ZnB dopants and PEDOT:PSS. Wavenumbers 650-4000 cm À1 in the transmittance mode were scanned with a resolution of 2 cm À1 and 16 scans.…”
