Extensive developments on the colloidal zero-dimensional semiconductor nanocrystal quantum dots (QDs) have led to various applications in the field of optoelectronics, such as QD-based light-emitting diodes,  high-efficient solar cells,  biological labels and detections, and quantum information systems,  primarily due to the QD’s high quantum yield, size-dependent spectral tunability, and environmental and temperature stability. Yet, a considerable carrier loss for the QDs as gain mediums will arise when compared to their counterpart semiconductors of bulk or higher dimensionality, which intrinsically constrains the required population inversion for achieving optical gain, and consequently hinders the stimulated emissions based on the colloidal QDs. In this talk, I will introduce our recent work  which demonstrates the capability of controlling the optical anisotropy of lasing emissions by manipulating the coupling strength spatially and spectrally between the oscillated electric field of emitted light and the localized surface plasmon (LSP) resonance for a random lasing medium composed of colloidal CdSe/ZnS quantum dots (QDs) and ellipsoidal silver nanoparticles (Ag NPs). The achievement of spatial and spectral coupling of LSP resonance with colloidal QDs respectively by the spin coating thin QDs film on Ag NPs and control of the Ag NP geometry make the present system one of the promising candidates of colloidal QDs-based random lasers to achieve coherent and polarized lasing emissions.
