The new technology, named Fourier Ptychographic microscopy (FPM), provides a coherent imaging approach for achieving a wide-field and high-resolution result by circumventing optical space-bandwidth product (SBP) of the system.
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.
Recently, one of CIOMP’s research group, prof. SUN Zaicheng developed a simple route to synthesize highly fluorescent N doped carbon dots with blue, green and yellow emission with UV, blue and green light excitation.
Chinese Changchun Institute of Optics, Fine Mechanics and Physics (CIOMP) has developed a micro module containing four vertical-cavity surface-emitting lasers (VCSELs) capable of emitting 210W at 110A current injection in short-pulse operation. The foreign researchers commented that this is the highest value reported for a VCSEL module consisting of single emitters.
