The blue emitting long persistent phosphor (LPP) Li<sub>2</sub>ZnGeO<sub>4</sub> and green LPP Li<sub>2</sub>ZnGeO<sub>4</sub>:Mn<sup>2+</sup> were newly prepared by a high temperature solid-state reaction method.
Broadband shortwave infrared (SWIR) light-emitting diodes (LEDs), capable of advancing the next-generation solid-state smart invisible lighting technology, have sparked tremendous interest and will launch ground-breaking spectroscopy instrumental applications. Nevertheless, device performance is still suppressed by low quantum efficiency limited emission bandwidth critical phosphor layer. Herein, we report a high-performance Ni2+-doped garnet solid-solution broadband SWIR emitter centered at...
Magnetic-induced luminescence (MIL) is realized via a strain-mediated coupling strategy. MIL composite laminates composed of magnetic actuator and phosphor phases are developed. The performance tested under low fields at room temperature. results provide novel type promising luminescent material for developing some new concept devices.

Abstract An abnormal trap distribution and coordination geometry‐dependent multi‐band emission are discovered in chromium‐doped aluminates. The broadband persistent luminescence from 650–1100 nm peaking at 688 793 Cr 3+ ‐doped SrAl 12 O 19 is systematically studied via structural spectroscopic analysis. Solid state nuclear magnetic resonance allows the visualization of various configurations , thus offering possibility tailoring local geometry center to trigger control spectral parameter....
Temperature-sensing media based on the fluorescence intensity ratio (FIR) of upconversion materials that suffer from low sensitivity owing to small energy gap still have a need for new compounds with strong luminescence (UCL). In this work, series MSc2O4:Er3+/Yb3+ (M = Mg, Ca, Sr, and Ba) nanocrystals were prepared by hydrothermal method using NaOH alkaline solution. The structure, morphology, UCL characteristics investigated, red CaSc2O4:Er3+/Yb3+ sample was dramatically enhanced factor...
ZnS nanowire arrays have been prepared for the first time by direct-current electrodeposition into nanopores of porous anodic alumina membranes (AAMs), and growth mechanism is that metal cations are firstly reduced then react with elemental S to form in AAMs. The AAMs benefit formation sulfide nanowires.
An efficient near-infrared (NIR) downconversion has been demonstrated in CaSc2O4: Ce(3+)/Yb(3+) phosphor. Doping concentration optimized 1%Ce(3+)/5%Yb(3+) shows stronger NIR emission than doping also typical YAG: under 470 nm excitation. The from 900 to 1100 is enhanced by a factor of 2.4. In addition, the main peak Yb(3+) CaSc2O4 around 976 matches better with optimal spectral response c-Si solar cell. visible and spectra decay curves Ce(3+): 5d → 4f were used demonstrate energy transfer...

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.
