On May 11, 2017, the large telescope design team of the Photoelectric Detection Research Department in CIOMP accomplished the 2m SiC adaptive telescope’s integrated testing.
Light–matter interaction realized by plasmonic microstructures brings about a strong light confinement which means energy can be controlled under micro- or nano-scale, providing a versatile approach to tailor optical properties precisely.
In a convenient and fast method, full color luminescence CDots and their composite phosphors with high fluorescence quantum efficiency were achieved for white light LEDs application.
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.
