Description
The host sensitized near-infrared (NIR) emitting phosphor Sr2CaMoO6:Yb3+ was fabricated by the solid state reaction method. The structural refinement and Raman spectra elucidate that Yb3+ ions preferentially occupy Ca2+ sites. The phosphor can harvest ultraviolet (UV)-blue photons and exhibits intense NIR emission at around 1012 nm with full-width-at-half-maximum of 1635 cm-1. Moreover, the absolute NIR photoluminesence quantum yield (PLQY) is estimated to be about 9%. The Sr2CaMoO6:Yb3+ phosphor may be a promising luminescence downshifting material for improving the spectral response of solar cells in the UV region. (copyright 2014 WILEY-VCH Verlag GmbH and Co.
