Dual-channel mechano-phosphorescence, characterized by dual emission and ultralong organic phosphorescence, was achieved by strengthening the intra- and intermolecular interactions in the highly twisted structures to realize a combined locking effect.
The 3D density profile of a femtosecond kilo-ampere electron bunch from laser wakefield acceleration was detected by using advanced optical diagnostics and genetic algorithm.
We introduce an innovative quartz-enhanced multiheterodyne resonant photoacoustic spectroscopy technique that utilizes a quartz tuning fork to achieve resonant detection of a dual comb based on the photoacoustic effect.
We demonstrate free-space coupling to microtoroids using one objective to excite and collect scattered resonant light. We achieve Q-factors > 108 and perform sensing with an SNR > 26 dB.
We developed a geometric approach to identify highly anisotropic materials. This leads to the discovery of giant anisotropy of As2S3, enabling the record-small quarter-wave plate.
A time-domain excitation strategy for stimulated Raman scattering was achieved by manipulating vibrational wave packet interference. The new method enables simultaneous sub-mM level sensitivity and natural-linewidth-limit Raman spectra.
We have introduced Te-based all-2D heterojunctions as optically controlled terahertz modulators to significantly promote the device performances and elaborated their charge dynamics driven by substrate effect through first-principles calculations.
