Abstract

The low melting point of bismuth allows the fabrication of a lanthanide-doped Bi2SiO5 crystalline-core/glassy silica-shell system through a simple impregnation of MSNs followed by thermal treatment. The synthetic strategy could be used for the synthesis of a wide variety of bismuth-based nanosystems.
