A brilliant sandwich type fluorescent nanostructure incorporating a compact quantum dot layer and versatile silica substrates

A hydrophobic layer in silica'' structure was designed to integrate a compact quantum dot (QD) layer with high quantum yield into scalable silica hosts containing desired functionality. This was based on metal affinity driven assembly of hydrophobic QDs with versatile silica substrates and homogeneous encapsulation of organosilica/silica layers.
