In the current study, Prof. Qu’s team studied the anisotropic PL in hetero-atom doped CDots using polarization dependent femtosecond transient absorption spectroscopy and computational simulation.
The proposed method provides technical foundation for the low speed and high precision control of permanent magnet synchronous motor in 4 meter telescope.
Professor Songnan Qu and his team at CIOMP have developed strong orange emissive carbon nanodots (CNDs) with a fluorescent quantum yield of up to 46% – almost double that previously achieved for long-wavelength emissive CNDs. This work was recently published in the journal Advanced Materials.
The Changchun Institute of Optics, Fine Mechanics and Physics (CIOMP), Chinese Academy of Sciences, has successfully developed a silicon carbide (SiC) single mirror blank – a vital component for creating a large-scale telescope.
Professor LI Bin and his team at State Key Laboratory of Luminescence and Applications in CIOMP have developed red emissive 2D Cationic Covalent Organic Frameworks (COFs) with tunable porosity and pore sizes at nanoscale. This is the ?rst time that the stable cationic crystalline frameworks allowed for the fabrication of a series of charged COFs through ion exchange processes, which have potential applications in the fields of organic semiconductor devices and optoelectronic sensors. This work was recently published in Journal of the American Chemical Society (J. Am. Chem. Soc., 2016, DOI: 10.1021/jacs.5b13490). The first author is assistant professor Heping Ma. This work is supported by NSFC.
On November 11, 2016, the Bureau of Facility Support and Budget, Chinese Academy of Sciences, hosted a conference to mark the successful completion of the ‘Development of a Large-Scale High-Precision Diffraction Grating Ruling System’ project, one of the National R&D Projects for Key Scientific Instruments, at the Changchun Institute of Optics, Fine Mechanics and Physics .
