Aqueous pyruvate partly dissociates under deep ultraviolet irradiation but is resilient to near ultraviolet excitation [PDF]
Nature CommunicationsThe deep ultraviolet photochemistry of aqueous pyruvate is believed to have been essential to the origin of life, and near ultraviolet excitation of pyruvate in aqueous aerosols is assumed to contribute significantly to the photochemistry of the Earth’s ...

A superlens for the deep ultraviolet [PDF]
Applied Physics Letters, 2009 A superlens based on a single aluminum layer operating at deep ultraviolet (UV) wavelengths is investigated both, theoretically and experimentally. Using a wavelength of 157 nm double slits with a center-to-center separation of only 70 nm were experimentally resolved and simulations indicate a possible resolution down to 29 nm with experimentally ...

Deep-Ultraviolet Emissive Carbon Nanodots
Nano Letters, 2019 Deep-ultraviolet (DUV) emissive carbon nanodots (CNDs) have been designed theoretically and demonstrated experimentally based on the results of first-principles calculations using the density functional theory method. The emission of the CNDs is located in the range from 280 to 300 nm, which coincides well with the results of theoretical calculation ...

Ultrafast molecular photophysics in the deep-ultraviolet [PDF]
The Journal of Chemical Physics, 2019 In the landscape of ultrafast spectroscopic tools, the deep- and near-ultraviolet ranges (200–400 nm) have lagged behind due to the lack of tunability of both the pump and the probe pulses in this range. With the advent of novel nonlinear optical methods, this has now become possible. In this perspective, I will review some of the recent studies in the
