## Description
- description: Near-infrared nanophosphors have attracted attention due to their wide
application fields, including component analysis, bioimaging, and spectral converters
of sunlight for crystalline silicon solar cells (c-Si). Yb3+ ions exhibit near-infrared
(NIR) luminescence at around 1000 nm, which is consistent with the first biological
window and the maximum responsivity range of c-Si. Therefore, we focused on and
successfully synthesized Bi3+/Yb3+-doped NIR luminescence nanophosphors, RE2MoO6:Bi3+,Yb3+
(RE=Gd, Y, and Lu) and Gd2Mo1–xWxO6:Bi3+,Yb3+ (x = 0–0.5), utilizing a solvothermal
reaction process. All samples exhibit NIR luminescence of Yb3+ ions under ultra-violet
(UV) light excitation and broadband excitation due to the charge transfer transition
between the O 2p/Bi 6s and Mo 4d or W 5d orbitals, indicated by their optical
properties of photoluminescence (PL), PL excitation (PLE), and reflectance spectra.
Furthermore, to evaluate the contribution of the Gd2MoO6:Bi,Yb (GMO:Bi,Yb) nanophosphor
to the conversion efficiency of c-Si, a phosphor-converted film was made using
dimethylpolysiloxane (PDMS) and the GMO:Bi,Yb nanophosphor. The results showed
that the conversion efficiency of c-Si with the PDMS/GMO:Bi,Yb film is higher
than that of c-Si with the PDMS-only film. Based on these results, the utilization
of down-shifting nanophosphors is able to enhance the conversion efficiency of
c-Si, which could be beneficial in addressing future energy challenges.
