Abstract

Abstract A novel broadband near-infrared (NIR) phosphor LiInSi2O6:Cr3+ (LIS:Cr3+) is successfully synthesized via solid-state reaction. Its crystal structure, photoluminescence properties as well as the application in NIR phosphor-converted LEDs (pc-LEDs) are explored. The LIS:Cr3+ phosphor has two absorptions bands centered at ~460 and 670 nm, respectively. Under 460 nm excitation, it shows the broadband NIR emission peaking at ~840 nm with a full width at half maximum (FWHM) of ~143 nm. The optimum Cr3+ concentration is found to be ~6 mol%, whereas the intensity decrease at further increased Cr3+ content is attributed to the radiative energy transfer process. The LIS:0.06Cr3+ phosphor has a quantum yield of ~75% and can retain ~77% of the initial intensity at 150 °C. Highly efficient, thermally stable and broad NIR emissions of LIS:Cr3+ phosphors are caused by the Cr3+ preferential occupancy in [InO6] octahedron with weak crystal field but relatively strong rigidity. The NIR pc-LED is fabricated by combining the LIS:Cr3+ phosphor with the blue LED chip, which has the NIR output power of ~51.6 mW and the photoelectric efficiency of ~17.8% at 100 mA drive current. The results suggest that LIS:Cr3+ phosphors have great potential for applications in broadband NIR pc-LEDs.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
