Blue-shifted aggregation-induced enhancement of a Sn(iv) fluoride complex: the role of fluorine in luminescence enhancement.

A new type of blue-shifted aggregation-induced emission enhancement was observed for a Sn(iv) fluoride complex, resulting in strong emission in the solid state as compared with that in solutions. The fluorinated Sn(iv) complex has a significantly more intense emission efficiency compared to the chlorinated Sn(iv) complex, which is attributed to stronger σ bonding.

A semiconductor bulk material that emits direct white light.

A unique type of inorganic-organic hybrid semiconductor bulk material is capable of emitting direct white light. Their photoluminescence properties can be tuned precisely and systematically by modifying structures and composition. They could be used as a single-material light-emitting source in high efficiency white-light-emitting diodes.
