“…The structural readjustment within the glass network is responsible for the witnessed color variability. For the up-conversion emission at 799 nm excitation wavelength, the CIE coordinates of STAMB1 to STAMB5 glasses, in accordance with the reports of [ 78 , 79 ], fall in the white region with high color purity (>90%). Moreover, the white color purity of STAMB6 was found to increase.…”

“…The observed chromaticity trend points to the potential of the glasses for use as white-light generation materials. For the up-conversion emission (at 896 nm excitation), the colour coordinates of the Dy 3+ mono-doped glasses remained in the pinkish region of the cool-white domain, which agreed well with the earlier observation made on Dy 3+ -doped carboxy-benzenesulfonate complexes and Dy 3+ -doped lanthanide compounds [104,105]. However, the coordinates of SATB6 and SATB7 glasses were moved to the bluish zone of the cool-white region.…”

In the up-conversion nonlinear optical process, the absorption of lower energy photons causes the emission of photons at higher energy due to various mechanisms like sequential optical excitation, energy transfer, and nonlinear light-matter interaction processes. Improving the up- and down-conversion luminescence of different lanthanide-doped glasses via metallic nanoparticle embedment remains challenging. There has been no clear understanding of how copper oxide nanoparticles (CuONps) affect the spectroscopic properties of the Dysprosium ions (Dy3+)-doped and Dysprosium-Samarium ions (Dy3+-Sm3+)-co-doped glasses. Thus, new CuONps-infused strontium-telluro-aluminum-magnesium-borate glass samples were prepared using the standard melt-quenching technique with Dy3+ doping and Dy3+-Sm3+ co-doping. X-ray diffraction (XRD) analysis confirmed the samples' glassy nature. High-resolution transmission electron microscopy (HRTEM) provided the orientation and size distribution of the embedded nanoparticles in the glass hosts. The downconversion luminescence emission (at 350 nm excitation) corresponds to 4F9/2→6H15/2, 4F9/2→6H13/2, and 4F9/2→6H11/2 transitions in Dy3+. Judd-Ofelt calculations for the CuONps embedded sample showed significant radiative properties. A branching ratio of 79.6% was attained. The upconversion luminescence emission (at 896 nm excitation) bands corresponded to 4F9/2→6H15/2 and 4F9/2→6H13/2 transitions for the Dy3+-doped glasses. In addition, an intense peak due to the 4G5/2→6H7/2 transition in Sm3+ was observed in the co-doped glasses. It was determined that the increased up-conversion luminescence was related to localized surface plasmon resonance, energy transfer, and local field enhancements caused by CuONps inclusion. It was confirmed that excited state absorption and energy transfer mechanisms were involved in the up-conversion luminescence. Synthesized glasses may be helpful for upconversion displays, optical data storage, and solid-state lasers.

To provide new insights for understanding the influence of B site cations on the structure in chlorometallate materials of the form AB n+Cl n+2, we report novel organic–inorganic hybrid metallates (OIHMs) incorporating histammonium (HistNH3) dications and various transition-metal and main group B site cations. Single crystals of OIHMs with the basic formula (HistNH3M n+Cl n+2, M = Fe, Co, Ni, Cu, Zn, Cd, Hg, Sb, Sn, Pb, Bi) were grown and their structures characterized by single-crystal X-ray crystallography. HistNH3CoCl4, HistNH3ZnCl4, and HistNH3SbCl5 were crystallized in a non-centrosymmetric space group and were subsequently studied with piezoresponse force microscopy (PFM). While bulk measurements of crystals and poly(vinylidene difluoride) (PVDF)/metallate composite films exhibited low bulk response values, the surface-measured local response values using PFM were 5.17 pm/V for HistNH3CoCl4, 22.6 pm/V for HistNH3ZnCl4, and 2.9 pm/V for HistNH3SbCl5 compared with 2.50 pm/V for PVDF reference samples. The magnitudes of the d 33 coefficient, net dipole, and cation–Cl bond dipole obtained from the density functional theory calculations confirm the higher response in HistNH3ZnCl4 compared to HistNH3CoCl4. Density of states and crystal orbital Hamilton population analysis indicate that the higher net dipole in HistNH3ZnCl4 compared to HistNH3CoCl4 is due to the lower hybridization of the M–Cl bond.
