“…Recently, many Eu 3? -doped tungstate based lattices (as host for the Eu 3? activators that emit the red light) have been reported for possible application as red conversion phosphors examples include CdWO 4 [2,3], SrWO 4 [4,5], Y 6 WO 12 [6], KLa(WO 4 ) 2 [7], RbGd(WO 4 ) 2 [8], NaY(WO 4 ) 2 [9], NaGd(WO 4 ) 2 [10], Na 2 Dy 4 (WO 4 ) 7 [11], La 2 W 2 O 9 [12], ZnWO 4 [13], Ba 4 Na 2 W 2 O 11 [14], MgWO 4 [15], and Li 2 Mg 2 (WO 4 ) 3 [16]. Some of these materials require high amounts of the expensive europium activator.…”

“…Considering the doping sites, characteristics such as distance between dopants, coordinate numbers, relative spatial position and electrical environments are also important in order to fully understand the photoluminescence properties [17]. Many tungstate lattices when acting as hosts for Eu 3? activators have been shown to manifest excellent luminescent efficiency and color purity as well as having high average refractive indexes [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16]. Also this class of tungsten oxides can be considered as ideal host lattices for dopants as they possess high thermal, chemical and physical stability and in addition they can often be synthesized at low temperatures.…”

All the red emitting europium-doped silver tungstate a-Ag 2-3x Eu x WO 4 (x = 0.01-0.08 mol) phosphor reported herein crystalise as nanorods. The nanorods were structurally characterised by X-ray powder diffraction, Rietveld refinement, low temperature (20 to -190°C) micro-Raman spectroscopy . The morphology of the nanorods reported herein was confirmed by field emission scanning electron microscopy. The optical properties were studied using low temperature (20 to -190°C) high resolution laser excited upconversion and downconversion luminescence.

“…The first peak that occurred at 360 nm confirms the presence of Ce 3+ in the sample . The secondary peak appeared at 376 nm because of the charge transfer from oxygen to tungsten present in the sample . The emission at the violet region (411 nm) is idiosyncratic of the Ce 2 (WO 4 ) 3 material.…”

Herein, we have synthesized pristine and g-C 3 N 4assisted Ce 2 (WO 4 ) 3 via a facile hydrothermal method. The structure was confirmed with the standard JCPDS card. g-C 3 N 4 encapsulated the crystal and reduced the size. The Raman spectra revealed the presence of Ce−O, W−O stretching and bending vibrations. Electron hole transfer facilitation and controllable recombination were altered by g-C 3 N 4 heterojunction with cerium tungstate. Ce 2 (WO 4 ) 3 possessed a larger band gap. As g-C 3 N 4 was assisted, the band gap was reduced which facilitates Ce 2 (WO 4 ) 3 to utilize more visible light. The prepared photocatalysts were used to investigate the model pollutant removal with visible light. The pure Janus Green B sample showed lesser efficiency, as it does not show self-degradation under light. As Ce 2 (WO 4 ) 3 was added, it slightly improved the efficiency as it possesses lower electron hole transfer and high recombination. Thus, g-C 3 N 4 was composited with Ce 2 (WO 4 ) 3 to make heterojunctions which will enhance the photoexcited electron and hole transfer and decrease e − /h + recombination. The rate constant values of the photocatalysts were calculated, and the system follows the first-order pseudo-kinetic model. Ciprofloxacin, a well-known antibiotic, was also used to degrade under visible light. The pure sample showed lower efficiency, and the antibiotic was reduced well with the addition of prepared photocatalysts. The modification of Ce 2 (WO 4 ) 3 with the optimum-level g-C 3 N 4 facilitated electron hole charge transfer, and numerous adsorbed dye molecules on the photocatalyst surface made 0.1 g g-C 3 N 4 −Ce 2 (WO 4 ) 3 a plausible photocatalyst for the water remediation process.

Fluorescence Sensing Behavior for the Detection of Alcoholic Strength and Water Based on Two Novel Metallic Complex Edifices

Alcoholic strength is a fundamental variable in industry production and its determination is crucial in technological developments. This study offers a novel strategy for fluorescent sensing of alcoholic content based on a terbium coordination complex. In pure water, the emissive compound displays blue luminescence. However, the addition of ethanol into the aqueous solution has induced the recovery of terbium green emissions. In another case, the achieved Eu(III)-phenanthroline complex shows high sensitivity to solvent polarity and the detection of trace amount of water can be realized through an "on-off" change with a low detection limit of 32.4 ppm.
