Abstract Raising photoelectric conversion efficiency and enhancing heat management are two critical concerns for silicon-based solar cells. In this work, efficient Yb 3+ infrared emissions from both quantum cutting upconversion were demonstrated by adjusting Er concentrations, thermo-manage-applicable temperature sensing based on the luminescence intensity ratio of super-low thermal quenching levels was discovered in an /Yb co-doped tungstate system. The mechanism clearly decrypted as a...
A series of K1–2x–2yBayAl11O17(KBAO):xEu2+ phosphors are designed to develop a blue phosphor with excellent thermal properties. All the samples present similar β-Al2O3 structures P63/mmc space group; K+ vacancy can exist stably until Ba2+ concentration exceeds around y = 0.3. KBAO:Eu2+ exhibits strong absorption for near-ultraviolet light and relatively standard emission. The mechanisms excitation emission spectrum variations have also been studied in detail. Based on adjustment numbers...
Abstract The hosts with low maximum phonon energy (MPE) are preferred since the nonradiative consumption of luminescence centers in them low. Among MPE hosts, oxide ones more favored owing to their excellent stability and easy synthesis. In this work, optical spectroscopic properties BaGd 2 O 4 :Er 3+ phosphor were studied. host was observed from Eu sideband (PSB) spectrum Raman be 477 cm −1 which does not second fluoride hosts. refractive index, is indispensable for Judd–Ofelt calculation,...
With changing dietary habits and increasing awareness of the nutraceutical role foods, demand for natural plant proteins interest in non-traditional protein sources food industry are increasing. Industrial hemp, belonging to family Cannabaceae, is cultivated its fibre edible seeds. Due nutritional value, it has also been used medicine. In particular, hemp seed have drawn considerable attention both scientific industrial fields because their excellent values, superior digestibility, low...
Usually, the optical transition properties of trivalent rare earth (RE) ions in transparent hosts can be quantitatively investigated framework Judd-Ofelt theory. A standard and commonly accepted calculation procedure based on absorption spectrum has already been established. However, it is hard to assess RE doped powdered film materials owing difficulty absolute measurements. In this work, we proposed a new route calculate parameters ion-doped any morphological shaped forms. method,...
The optical transition properties of trivalent rare earth (RE3+) doped luminescent materials have received extensive attention. Judd-Ofelt theory is an effective tool for exploring the 4f-4f transitions lanthanides. aim this work to discover effect Er3+ concentration and different Ln3+ ions on parameters in LnOCl:Er3+ (Ln = Y, La, Gd) phosphors. Oxychloride phosphors were produced via a single displacement reaction technique. calculation procedure RE3+ powders was modified then adopted...
Abstract A photobiocatalytic cascade transforming natural triglycerides into alkanes/alkenes is proposed. Starting from triglycerides, free fatty acids have been obtained using lipases. The were then, in a photoenzymatic step, decarboxylated the C1‐shortened alkanes recently described photodecarboxylase Chlorella variabilis NC64A. This produced various (waste) oils significant amounts (up to 24 g L −1 ) and may provide basis for valorisation of waste next generation biodiesel.
Abstract Technological progress has promoted the development of ultra‐wide near‐infrared (NIR) luminescent materials as a new NIR light source. The emission in Na(Al,Ga) 11 O 17 :xCr 3+ (NAGO:xCr ) phosphors is achieved by constructing unique Cr ‐Cr ion pair confined structure. pairs can be observed at low concentration ions(x = 0.04), increase Ga would promote formation pairs, thereby effectively enhancing energy migration process from high‐energy ions to low‐energy ones. Herein, full width...
A WLED prototype was assembled using a 310 nm LED chip combined with prepared green SYT: Tb 3+ phosphor and the other two commercial blue red phosphors. The obtained warm white light exhibits good chromaticity coordinates high color rendering index.
Abstract We have fabricated CsPbBr 3 perovskite quantum dots (QDs) in a multi‐component borate glass by melt‐quenching technique. Transmission electron microscopy (TEM) reveals cubic phase crystal for QDs. As the treatment temperature or time duration increases, photoluminescence (PL) peak shifts to long wavelength range of 510 525 nm, and full width at half‐maximum varies 24 18 nm. The absorption edge low energy side 2.54 2.41 eV. different excitation spectra (PLE) reflect change...
