C-dots Luminescence Introduction:

Carbon dots (CDs), an emerging class of carbon based luminescent nanomaterials, have drawn increasing attention owing to their extensive applications in various fields, such as bioimaging, biosensors, optoelectronics, laser, catalysis, and so forth. CDs possess several distinct merits, such as tunable emission, high photostability, low cost, and low cytotoxicity. Especially, CDs-based composites with strong photoluminescence are much desirable due to their special applications, such as color convert layer in light-emitting diode (LED). In our research group, there are two associate professors, including Ding Zhou and Di Li. Our group focuses on designing structured nanoscale materials with exceptional properties. Our group fabricates fluorescent nanomaterials by tuning the size and shape at the nanoscale.

Low Dimensional OpticalIntroduction:

Our work focus on the design, growth, optical characterization of semiconductor nano-materials and the fabrication of related optoelectronic devices. In 2013, we fabricated the artificial leaf like structures self-assembled by ZnO nanoparticles, which has enhanced the light absorption of ZnO material. The photocurrent on/off ratio of the corresponding UV photodetectors was 4 orders of magnitude (Wang Fei, Zhao Dongxu*, et. al., Nanoscale, 2013, 5, 2864-2869). Meanwhile, we fabricated the ZnO 2D photonic crystals with the PS micro spheres as template, by using Mie scattering theory, we accurately simulated the photonic band structure and the corresponding change rules, which is in well accordance with the experimental data. The ZnO 2D photonic crystals presents the enhanced absorbance in visible region, and the visible light driven photocatalysis was achieved (Wang Fei, Zhao Dongxu*, et. al., J. Mater. Chem. A, 2013, 1, 9132-9137). In 2014, we began to design and growth the ZnO/Ga2O3 core/shell microwires by one-step CVD method, and the related solar-blind photodetector show the responsivity of 1.3*10^3 A/W, on/off ratio of 10^6 and the detectivity of 9.91*10^14 Jones (Zhao Bin, Wang Fei, et. al., Nano letters, 2015, 15, 3988; Zhao Bin, Wang Fei, et. al., Adv. Funct. Mater. 2017, 27, 1700264). Recent years, I was interested in the perovskite materials and related properties. In 2016, we fabricated a photoconductive photodetector based on the organometal halide perovskites, and the fast respond speed of less than 20 μs was achieved (Wang Fei, Mei Jingjing, et. al., ACS Appl. Mater. Inter., 2016, 8, 2840-2846). Then, from the ultrafast femtosecond transient absorption spectra, we have observed the energy transfer process between CsPbBr3 quantum dots and solvents (Mei Jingjing, Wang Fei*, et. al., J. Mater. Chem. C, 2017, 5, 11076). Recently, we focus on the CVD growth of CsPbX3 and CsSnX3 materials, and the self-powered all-inorganic photodetectors with high performance was obtained (Tian Cancan, Wang Fei*, et. al., ACS Appl. Mater. Inter., 2019, 11, 15804-15812).
