Highly uniform core/double‐shell‐structured β‐NaYF 4 :Er 3+ ,Yb 3+ @SiO 2 @TiO 2 hexagonal sub‐microprisms are prepared and employed in dye‐sensitized solar cells (DSCs) internally. This work paves a facile way to enable the most‐efficient upconversion material (β‐NaYF 4 :Er 3+ ,Yb 3+ ) to be used as scattering and upconversion centers in the photoelectrode of a DSC.
