Ural Federal University (UrFU) Institute of Physics and Technology in Yekaterinburg, Russia contracted McPherson (Chelmsford, MA USA), a manufacturer of ultraviolet spectrometers, to provide a VUVAS instrument in support of the UrFU scientific development program. The new VUVAS PLUS Spectrophotometer system works from 115nm vacuum ultraviolet to 1800nm infrared. The new system measures transmittance and reflectance at adjustable angles. Plus it delivers tunable vacuum ultraviolet (VUV) excitation light to samples with emission measured in the visible and near infrared. A high vacuum environment keeps samples clean and prevents absorption by atmospheric gases and water vapor. A liquid Helium cryostat allows cooling samples during measurements.

The UrFU research group “Functional Materials and Structures for Photonics & Optoelectronics” led by Prof. A. Zatsepin (members Dr. E. Buntov, Dr. D. Biryukov, Dr. A. Slesarev, Dr. D. Zatsepin) studies radiation physics and spectroscopy of disordered and low-sized systems (glasses, single crystals, thin films, quantum dots). Currently the team is working on various host matrices containing nanometer scale particles formed by high-energy pulsed irradiation. They plan to measure optical and luminescence properties of advanced functional materials with the new VUVAS PLUS spectrophotometer. The scientific results obtained constitute a basis for new materials development with various applications for integrated optics, micro-, optoelectronics and photonics.
