Tunable Emission

ABSTRACTA series of Ce3+ doped Ca8La2(PO4)6O2 phosphors with tunable emission were successfully synthesized by traditional solid state reaction. The crystal structure and photoluminescence properties were studied through X-ray diffraction, photoluminescence excitation and emission spectra. The results indicated that Ca8La2(PO4)6O2:Ce3+ exhibited color-tunable emission due to the 5d-4f transitions of Ce3+ ions under different wavelength excitation. The optimal doping content of Ce3+ ions in Ca8La2(PO4)6O2 was found to be 5 mol%. The site-selective photoluminescence property and the reason for red-shift of the emission band along with Ce3+ content and the excitation wavelength were also studied in detail.

Single-crystal X-ray diffraction reveals a series of phosphorescent cocrystals which were assembled by 1,4-diiodotetrafluorobenzene (1,4-DITFB) and either 4,7-dimethyl-1,10-phenanthroline (DMPhe), 4,7-diphenyl-1,10-phenanthroline (DPPhe) or 4,7-dichloro-1,10-phenanthroline (DClPhe)viaC—I...N halogen bonding. These cocrystals, labeled (1), (2) and (3), respectively, are phosphorescent and a distinct change in phosphorescent color can be observed from orange–yellow, green to yellow–green, with well defined vibrational band maxima at 587, 520 and 611 nm for (1), (2) and (3). Based on the dependence of halogen bonding in sites and strength, we discussed the impact of substituents with different electron-withdrawing effects and steric hindrance on intermolecular noncovalent interactions and phosphorescence. The method of inducing and modulating phosphorescence by halogen bonding and other weak non-covalent interactions through changing the substituent groups of molecules should be significant in both theory and the application of optical function materials with predictable and modulated luminescent properties.

Sol Gel Synthesis

Pure Zn2SiO4 and Vanadium doped Zn2SiO4 green nanophosphor materials were synthesized using sol–gel method and thermally annealed at 1500 °C. The structural, morphology and optical properties were characterized using various techniques; X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), Scanning electron microscope (SEM), high resolution transmission electron microscopy (HTEM), and photoluminescence spectroscopy (PL). XRD results shown β-Zn2SiO4 phase with triclinic structure that obtained after the heat treatment of samples at 1500 °C. The PL spectrum of V-Zn2SiO4 shows an intensive emission band in the visible region centered at 526 nm. This band is related to presence of vanadium in the interfaces between Zn2SiO4 nanoparticles and the host matrix, SiO2. The interesting of these nanophosphors were attributed for its capability of showing color-tunable emissions in visible region under a single-wavelength excitation.
