A generalized one-step synthesis strategy is proposed for preparing monolithic silica/block copolymer mesostructured composites doped with different metal sulfides. The materials were characterized by small-angel X-ray diffraction (XRD) and ultraviolet-visible diffused reflection spectra (UV-DRS). The results show that the long-range regularity of the mesostructured silica hosts and the quantum-confined effect of the small-sized semiconductive metal sulfides are well combined for the derived composites, which makes the composites possess tunable optical properties.
