A copolymer has been used as a template for enhanced optical properties of core-shell CdS/ZnSe quantum dots doped cholesteric liquid crystal. The lasing behavior is achieved at relatively low laser excitation energy threshold at room temperature. Low-threshold value and high-optical stability make this optical system promising for visible laser emitter applications.
