Composition dependent structural and optical properties of PbF2–TeO2–B2O3–Eu2O3 glasses

In Situ Crystallization Synthesis of CsPbBr3 Perovskite Quantum Dot-Embedded Glasses with Improved Stability for Solid-State Lighting and Random Upconverted Lasing

“…X-ray photoelectron spectroscopy (XPS) measurements evidence the existence of Te, B, Al, Zn, O, Na, Cs, Pb, and Br signals, and the slight shift of Cs, Pb, and Br peaks toward larger binding energy after glass crystallization probably attributes to the modification of ligand fields surrounding these elements (Figure S3). Fourier transform infrared (FTIR) spectra (Figure S4) confirm that glass network structure mainly consists of [TeO 4 ], [BO 4 ], and [BO 3 ] units, where the related stretching vibrations of Te–O and B–O bonds are clearly observed. , As a supplement, Raman spectra of PG and QDs@glass samples were recorded to trace the structural variation after glass crystallization. As shown in Figure b, both PG and GC exhibit similar strong peaks at 753, 670, and 472 cm –1 assigned to stretching vibration of TeO 4 trigonal bipyramid and stretching and bending vibrations of Te–O–Te group.…”

“…After exploring tremendous fundamental glass compositions and perovskite-related components, TeO 2 -based inorganic glasses are adopted as hosts, Cs 2 CO 3 −PbBr 2 −KBr (CPK) and CsBr−PbBr 2 (CP) serve as the source of perovskites, as tabulated in Tables S1 and S2, respectively. The melting 37,38 As a supplement, Raman spectra of PG and QDs@glass samples were recorded We further studied the optical properties of CsPbBr 3 QDembedded glass. The precursor glass is transparent and colorless and gradually turn to be translucent and light yellow after glass crystallization (Figure S5), indicating the successful growth of QDs among glass matrix.…”

“…Similar observations were also reported by other researchers. [54][55][56] 3.1.3 Photoluminescence (PL) studies. Fig.…”

Effect of Y3+ on the structural and photoluminescence properties of yttrium‐doped sodium borate glass

“…To learn more about the compactness of the glass matrix, the following groups of equations [ 35 ] were used to calculate the concentration of rare earth ions ( N Y ) in the host matrix: where N A is Avogadro's number. The polaron radius ( r p ) may be computed for the rare earth (RE) ion concentration: The interionic distance ( r i ) between the RE ions in a continuous random network of host glass material can be estimated by the following formula: In addition, the following equation [ 33 ] determined the field strength ( F ) corresponding to the Y ions: where Z is the valence of the Y ion.…”

“…[7] Furthermore, the continuous addition of Y 2 O 3 at the expense of Na 2 O increased the number of oxygen ions in the glass matrix, and may have resulted in an increase in the oxygen packing density (OPD) and a drop in the V m values. [34] To learn more about the compactness of the glass matrix, the following groups of equations [35] were used to calculate the concentration of rare earth ions (N Y ) in the host matrix:…”
