Characterization of phosphorus compounds in soils by deep ultraviolet (DUV) Raman microspectroscopy
Journal of Raman Spectroscopy, 2017 Deep ultraviolet Raman microspectroscopy was successfully investigated as a new approach to analyze the chemical state of phosphorus compounds directly in soil. We demonstrate that ultraviolet excitation has the advantage to avoid the interference with the strong fluorescence, which occurs in the visible spectral range caused by organic matter in soils.

Tuning the Plasmonic Resonance Peak for Al Nanorods on AlGaN Layer to Deep Ultraviolet Band
IEEE Photonics Journal, 2021 Tuning the plasmonic resonance peak to the deep ultraviolet (DUV) band is critical for plasmonic-enhanced AlGaN-based DUV photodetector. However,the high refractive index of AlGaN layer seriously limits the plasmonic resonance peak in DUV band. Therefore,
