Abstract Upconversion (UC) of lanthanide-doped nanostructure has the unique ability to convert low energy infrared (IR) light to high energy photons, which has significant potential for energy conversion applications. This review concisely discusses the basic concepts and fundamental theories of lanthanide nanostructures, synthesis techniques, and enhancement methods of upconversion for photovoltaic and for near-infrared (NIR) photodetector application. In addition, a few examples of lanthanide-doped nanostructures with improved performance were discussed, with particular emphasis on upconversion emission enhancement using coupling plasmon. The use of UC materials has been shown to significantly improve the NIR light-harvesting properties of photovoltaic devices and photocatalytic materials. However, the inefficiency of UC emission also prompted the need for additional modification of the optical properties of UC material. This improvement entailed the proper selection of the host matrix and optimization of the sensitizer and activator concentrations, followed by subjecting the UC material to surface-passivation, plasmonic enhancement, or doping. As expected, improving the optical properties of UC materials can lead to enhanced efficiency of photodetectors and photovoltaic devices.

The spontaneous emission rate of a two-level system quantum dots is not intrinsic properties of the emitter itself but is molded by the electromagnetic environment that surrounds it. Photonic crystal micro cavity can conveniently shape the states of electromagnetic modes by providing modes with the required small volumes and high quality factors. This paper studies spontaneous emission from quantum dots embedded in photonic crystal micro cavity, and introduces the coupling characters of photonic crystal and quantum dot, and analyses the effectiveness of spontaneous emission enhancement from quantum dots embedded in photonic crystal micro cavity in detail. The research of this paper provides a basic reference for dynamic control of optics quantum systems.
