Pure Red Emitting Composites with Nearly 100% Solid–state Photoluminescence Quantum Yield Obtained by In-situ Growth Sr2+- doped Hybrid Halides CsPb(Br,I)3 Perovskite Quantum Dots in Mesoporous Silica Red emitting composite peaking around at 635 nm with a near-unity photoluminescence quantum yield (PLQY) and a full width at half maximum (fwhm) of 35 nm was achieved through the in-situ growth of Sr2+-doped CsPb(Br0.4I0.6)3 perovskite quantum dots (PeQDs) within mesoporous silica.
