Multifunctional lanthanide-based upconversion nanoparticles (UCNPs), which feature efficiently convert low-energy photons into high-energy photons, have attracted considerable attention in the domain of materials science and biomedical applications. Due to their unique photophysical properties, including light-emitting stability, excellent upconver...
A variety of 0-20 mol% of molybdenum ions (Mo 3+) doped sodium Rare-Earth (RE) fluoride upconversion nanowires (UCNW) were prepared by Coprecipitate-Solvothermal Ion-Exchange (CSIE) method. In this study, the Mo 3+ doped rare-earth hydroxide [REMo(OH)3] precursors were synthesized by the coprecipitation-solvothermal method. Following, the hexagonal...

In this work, the upconversion temperature sensing was used to study the light-emitting properties of Gd2(MoO4)3:Y3+/Yb3+/Er3+-based LED. In order to obtain high-intensity upconversion luminescence, we studied the effect of Y3+ doping concentration on the photon upconversion of Yb3+/Er3+-activated Gd2(MoO4)3 under 940 nm excitation. We also explore...

The effect of novel silver nanowire encapsulated NaGdF4:Yb,Er hybrid nanocomposite on the upconversion emission and bioimaging properties has been investigated. The upconvension nanomaterials were synthesised by polyol method in the presence of ethylene glycol, PVP and ethylenediamine. The NaGdF4:Yb,Er-Ag hybrid was formed with upconverting NaGdF4:...

Removal of hazardous NO at low temperature via photo-assisted selective catalytic reduction (photo-SCR) strategy is promising, however fully harvesting of solar energy and achieving high SO2/H2O tolerance still remain a challenge. Herein, the phosphoric acid modified natural attapulgite(P-ATP) was employed as a matrix to immobilize CeVO4 by microwa...

Hot-band absorption and anti-Stokes emission properties of an organic fluorescent dye, Alexa Fluor 568, were characterized and compared with those of Rhodamine 101. The comparison of the properties (e.g., quantum efficiency, spectral distribution, thermal properties, and fluorescence lifetime) between the two dyes confirms that both dyes undergo th...

Triple-negative breast cancer (TNBC) is a subtype of breast cancer in which the estrogen receptor and progesterone receptor are not expressed, and human epidermal growth factor receptor 2 is not amplified or overexpressed either, which make the clinical diagnosis and treatment very challenging. Molecular imaging can provide an effective way to diag...

The homogenous Er3+/Yb3+-codoped NaGdF4 nanorods were prepared through an ingenious reaction technology at room temperature. The influence of synthetic time on the phase category and microstructure of the studied compounds was examined in detail. When the reaction time was 3 h, the Er3+/Yb3+-codoped NaGdF4 nanorods with single hexagonal phase were ...

We investigated the doping-site dependence of photoluminescence and upconversion (UC) emission characteristics of Ho3+ and Yb3+ co-doped BaHfO3 polycrystals. Under 980-nm near-infrared excitation, we detected sizable green (550 nm) and red (660 and 760 nm) UC emissions from Ho3+ ions based on the assistance of Yb3+ ions as sensitizers. These emissi...
Upconversion (UC) is the process by which the energy of multiple photons is absorbed by a compound and restored in the form of a photon of higher energy than the incident light, resulting in an anti-Stokes process. Although studied theoretically since the middle of the last century and experimentally observed in the 1960′s, the process was up to re...
