Polymer composite film for ultrafast photonics

Polymer composite films, particularly those based on polymers and layered nanomaterials, are attractive materials for exploiting the properties of multiple materials for applications in electronics and photonics. Recently, scientists have found that beta-lead oxide quantum dot /polystyrene composite films exhibit excellent stability in high humidity and strong saturable absorption response from visible to the near-infrared region. This makes them an attractive material for practical applications in optoelectronic devices in marine environments and other harsh condition, such as humid weather.
