AIEgens represent a special class of molecules, which are emissive in aggregated state, but show almost no fluorescence in dissolved form. Herein we report on the aggregation-induced emission properties of scandium complex with 2-naphtoyltrifluoroacetone ([Sc(NTA)3]). Fluorescence quantum yield of the complex increases ∼68 times, from 0.005 to 0.34...

The influence of phosphate content on the formation and luminescent properties of Er³⁺/Yb³⁺-doped fluorophosphate glass has been studied. Using the Judd-Ofelt theory the phenomenological intensity parameters Ωt (t = 2; 4; 6) were obtained. The change of Judd-Ofelt parameters indicates minor differences in Er³⁺environment with increase in the phosph...

The model of a fiber optic sensor device which operational principle is based on the thermal quenching of luminescence for ambient temperature measurements was experimentally studied. The construction of a multimode optical fiber with a transmission of more than 90%/m in the spectral region from 350 to 650 nm and a quartz capillary filled with a ph...

The treatment of monodisperse carbon nanodots (MCNDs) with combination of aqueous ammonia and hydrogen peroxide is found to result in a prominent enhancement of their fluorescence efficiency. Depending on the hydrogen peroxide concentration the increase of the MCNDs quantum yield of up to seven-fold has been achieved. Considering the absence of pro...

The fluorescence effect of the scandium compounds with 2-naphthoyltrifluoroacetone on solvent composition was studied. The earlier unknown increase in fluorescence quantum yield of scandium diketonate was observed under the change of solvent from dimethylformamide to water. The increase in quantum yield of fluorescence was interpreted as the conseq...

The structure and properties of transparent ZnO–SnO2 photocatalytic coatings formed on glass surfaces by the polymer–salt method are studied. The physical and chemical processes occurring during formation of the coatings are studied by differential scanning calorimetry and X-ray diffraction analysis. The structure and optical properties of the obta...

Photopolymer luminescent compositions containing chelate complexes of Eu ³⁺ with 2-naphthoyltrifluoroacetone and trioctylphosphine oxide as a luminescent dopant have been developed for the photopolymer-based 3-D printing techniques. Photocured samples of photopolymer compositions are transparent in the visible range and have bright red luminescence...
