Ultraviolet‐visible (UV‐vis) absorption, flash photolysis, and 1H and 13C NMR spectroscopy were used to investigate the mechanism of formation and structure of complexes in the 1',3',3'‐trimethylspiro[2H‐1‐benzopyran‐2,2'‐indoline] (SP, also well known as BIPS) with Al3+ (inorganic salts) in ethanol (EtOH), methanol (MeOH), and in aqueous MeOH solutions. A labile (equilibrium constants ≤ 5000 M−1) complex of SP and Al3+ with broad absorption band in the UV‐vis with λmax = 380 nm appeared promptly in the presence of an excess of Al3+. The slow formation of a stable complex (SC) between Al3+ and two merocyanine (MC) forms of SP with an intensive absorption band at λmax = 430 nm is observed with a yield of 1.0 upon keeping the solutions of these two compounds at constant concentration ratio [Al3+] ≥[SP]/2 in the dark. The rate constants of such SC formation were close to the corresponding rate constant of the transformation of SP into MC in the dark (5.0×10−5‐1×10‐3 s‐1, depending upon the solvent). The photolysis of the SC with visible light (λ > 400 nm) results in the total conversion of the SC into SP. The SC forms promptly after the addition of Al3+ at concentrations of the same order as those of MC. This method allows detection of [Al3+] to concentrations as low as 50 nM. The kinetics and thermodynamic parameters of the SP and MC reactions and of their complex formation with Al3+ are discussed.

“…Fluorescent chemical sensors with high sensitivity, good selectivity, high speed and simplicity properties are widely used in recent years . Even though some advancements have been made in designing and applying molecule‐based fluorescent probes, high response, high sensitivity and dual‐functional probes are still requirement for practical utilization . Therefore, it is urgent to develop a fluorescent probe that has the characteristics of simple synthesis, fast response, high sensitivity, and can meet the dual‐function identification requirements …”

A high-efficiency dual-functional on-off-on fluorescence probe: 2'-4'-dihydroxydiphenyl-8-formyl-7-hydroxycoumarin hydrazine (L) based on photoelectron transfer mechanism (PET) was designed and synthesized, and its ion recognition characteristics were fully studied by spectroscopy. As expected, probe L shows highly sensitive to Cu 2 + in EtOH-HEPES (20 mM v/v, 80 : 20, pH = 7.40) solution, and its detection limit up to 6.14 × 10 À 7 M. The stoichiometric ratio of LÀ Cu 2 + complex was determined as 1 : 1 based on 1 H NMR titration and ESI-MS. Meanwhile, the resulted LÀ Cu 2 + complex shows good selectivity for the phosphoric acid family anion (H 2 PO 4 À , HPO 4 2À and PO 4 3À ), which denote probe L the dual-function in rapid detection of Cu 2 + and phosphate family's ions.

“…The devices are commonly fabricated by using light-emitting-diodes (LEDs) and phosphors. Because LEDs have virtues of energy-saving, environmental friendliness and high efficiency [1][2][3][4][5][6]. Currently, W-LEDs are realized by combining the output from the blue LED chip with the yellow-emitting phosphor Y3Al5O12:Ce 3+ phosphor.…”

Various novel Ba2Y3(SiO4)3F:Tm3+ blue-emitting fluorosilicate materials were achieved via solid-state synthesis. The structure and phase purity of prepared Ba2Y3(SiO4)3F:xTm3+ (x = 0.001-0.10 mol) were examined by X-ray powder diffraction. The surface morphology of Ba2Y3(SiO4)3F:0.01Tm3+ was studied by scanning electron microscopy. Photoluminescence properties were systematically explored under the monitoring emission (λem = 468 nm) and excitation (λex = 302 nm) spectra. The optimum mole ratio of as-synthesized phosphors was 0.01 mol. The concentration quenching mechanism in the Ba2Y3(SiO4)3F host was due to electric multipole interaction. Particularly, the chromaticity coordinates (0.1334, 0.0474) of Ba2Y3(SiO4)3F:0.01Tm3+ are near to those of the commercial BaMgAl10O17:Eu2+. These results validated the Ba2Y3(SiO4)3F:Tm3+ fluorosilicate phosphor can be used as a good blue-emitting candidate for W-LEDs.
