AbstractNovel luminescent materials Ca3-xSi2O7: xPr3+ were successfully prepared by the high-temperature solid-state method. The crystal structure, morphology, and optical spectrum were characterised by X-ray diffraction (XRD), scanning electron microscopy (SEM), and spectroscopy, respectively. The XRD patterns of the samples indicate that the crystal structure is monoclinic symmetry. The SEM shows that the selected sample has good crystallinity although its appearance is irregular and scalelike. The peak of the excitation spectrum of the sample is located at around 449 nm, corresponding to 3H4→3P2 transition of Pr3+. The peak of the emission spectrum of the sample is situated at around 612 nm which is attributed to 3P0→3H6 transition of Pr3+, and the colour is orange-red. The optimum concentration for Pr3+ replaced Ca2+ sites in Ca3Si2O7: Pr3+ is 0.75 mol%. The lifetime (8.48 μs) of a typical sample (Ca2.9925Pr0.0075)Si2O7 is obtained. It reveals that orange-red phosphors Ca3-xSi2O7: xPr3+ possess remarkable optical properties and can be used in white light emitting devices.

State Method

Cr[Formula: see text]-doped zinc gallate (ZnGa2O4) near-infrared (NIR) phosphors were synthesized via a high temperature solid state method. The luminescence properties of the phosphors were studied systematically. A significant spectra overlap between the emission of ZnGa2O4 and the absorption of Cr[Formula: see text] was observed and 300 nm excitation exhibited the most excellent long-lasting luminescence properties among the three main excitation bands. Luminescence intensity was changed with the ratio of Ga[Formula: see text]/Cr[Formula: see text] and the blue host emission of ZnGa2O4 was suppressed when doping Cr[Formula: see text] into ZnGa2O4. The fluorescence decay curves of blue emission of ZnGa2O4 with different Cr[Formula: see text] doping concentrations indicated that the lifetime of ZnGa2O4 at 505 nm become shorter with the increase of the Cr[Formula: see text] concentration. Herein, a possible mechanism of long-lasting luminescence in ZnGa2O4: Cr[Formula: see text] was proposed that the NIR long-lasting luminescence in ZnGa2O4: Cr[Formula: see text] comes from the persistent energy transfer from ZnGa2O4 to Cr[Formula: see text].
