Multifunctional near-infrared emitting Cr<sup>3+</sup>-doped Mg<sub>4</sub>Ga<sub>8</sub>Ge<sub>2</sub>O<sub>20</sub>particles with long persistent and photostimulated luminescence, photochromic properties.
A super-long-persistent phosphor Ba<sub>2</sub>SiO<sub>4</sub>:Eu<sup>2+</sup>,Ho<sup>3+</sup> and photostimulable luminescence for optical information storage.
Abstract Lead halide perovskites have emerged as superstar semiconductors owing to their superior optoelectronic properties. However, the issues of chemical and thermodynamic instability toxicity are yet be resolved. Here, non‐ Bi 3+ ‐doped all‐inorganic lead‐free perovskite derivatives reported. Most remarkable is successful extending excitation Cs 2 ZrCl 6 match with commercial near ultraviolet light‐emitting diode chips via deliberate aliovalent doping. The blue emission, contrary...
In the current "big data" era, state-of-the-art optical data storage (ODS) has become a front-runner in competing technologies. As one of most promising methods for breaking physical limitation suffered by traditional ones, advance optically stimulated luminescence (OSL) based technique is now still limited simultaneous single-level write-in and readout same spot. this work, to bridge data-capacity gap, we report first time novel nonphysical multidimensional OSL-based ODS flexible medium...
A dual‐emission ( UV /Visible) phosphor SrZrO 3 : Pr 3+ was prepared by a high‐temperature solid‐state reaction method. The afterglow including ultraviolet ) and visible region which originated from self‐trapped excitons f – transitions in first observed after the short ‐irradiation. All as‐prepared phosphors were studied systematically X ‐ray diffraction, photoluminescence PL spectra, decay curves, long spectra LAG ), thermoluminescence TL glow curves. intensity performance of are dependent...
Photochromic materials have attracted increasing interest as optical switches and erasable memory media.
We gained insight into the temperature-dependent relative emission intensity of La<sub>3</sub>GaGe<sub>5</sub>O<sub>16</sub>: Mn<sup>4+</sup>phosphor, and luminescence quenching temperature activation energy for thermal (Δ<italic>E</italic>) were obtained.
Abstract A single‐phase full‐color emitting phosphor Na 3 Sc 2 (PO 4 ) :Eu 2+ /Tb 3+ /Mn has been synthesized by high‐temperature solid‐state method. The crystal structure is measured X‐ray diffraction. emission can be tuned from blue to green/red/white through reasonable adjustment of doping ratio among Eu ions. photoluminescence, energy‐transfer efficiency and concentration quenching mechanisms in ‐Tb /Eu ‐Mn co‐doped samples were studied detail. All as‐obtained show high quantum yield...
We investigated the persistent luminescence in europium-doped barium chloroapatite upon codoping with cerium. Luminescence properties of phosphors, including photoluminescence, decay, and thermoluminescence are systematically studied. This material holds key to unsettled questions field luminescence. formulated a model on basis experimental results. In our model, some Eu2+ ions oxidized Eu3+ under short UV excitation, released electrons trapped at positive substitutional defect introduced by...
