研究领域

Our research programme aims at exploiting the physical and chemical property of lanthanide elements motivated by the creation of novel luminescent nanomaterials. Our research activities include the synthesis, characterization, and applications of nanostructured materials compring luminescent lanthanide ions. We develop chemical methods for synthesizing new nanocrystals, nanoarchitectures, and nanocomposites. Extensive characterizations of the nanoparticles are carried out with microscopy and spectroscopy techniques. 1. Nanocrystal and nanostructure chemistry A central theme in nanoresearch is to synthesize high quality nanoparticles with exquisite control over particle size, shape, and structure. For doped nanoparticles, the control of dopant cocnentration and distribution (spactial confinement) are of particular interest. Our research goal is to develop new chemical methods to rationally assemble atoms/ions at the nanometer scale towards ''Lab on a Particle'' architectures for better understanding and control of interplay of atomic/ionic interactions. By making sense of the shape, chemical composition, and structural complexity and anisotropy, one can fine tune the properties of nanomaterials to meet specific needs in practical applications. 2. Optical spectroscopy of nanoparticles The spectroscopic properties of lanthanide-doped bulk materials have been extensively studied and well documented. In nanoparticles, however, the effect of host structure appears as a new paramter that strongly affect optical transtions of lanthanide ions and need systematic investigation. We employ steady-state and time-resolved ultrafast spectroscopy in combination with high resolution microscopy to reveal the structure-property relationship of lanthanide-doped luminescent nanoparticles. The in-depth understanding of excited states dynamics of lanthanide ions in nanostructured hosts is a critical prereuitsite to deleberately tailoring their properties for rational construction of novel luminescent nanomaterials.
