High Sensitivity Singlet Oxygen Luminescence Sensor Using Computational Spectroscopy and Solid-State Detector

Tiffany C. Yu, Steve J. Davis, Mark T. Scimone, John P. Grimble et autres

This paper presents a technique for high sensitivity measurement of singlet oxygen luminescence generated during photodynamic therapy (PDT) and ultraviolet (UV) irradiation on skin. The high measurement sensitivity is achieved by using a computational spectroscopy (CS) approach that provides improved photon detection …

Do group 1 metal salts form deep eutectic solvents?

Andrew P. Abbott, Carmine D’Agostino, Steve J. Davis, Lynn F. Gladden et autres

Group 1 salts were compared with quaternary ammonium chlorides for their ability to form deep eutectic solvents and it was found that while some formed liquids the sodium ions caused the liquids to become structured and increased their viscosity.

ElectricOIL discharge and post-discharge kinetics experiments and modeling

Andrew D. Palla, Joseph W. Zimmerman, Brian Woodard, David L. Carroll et autres

Laser oscillation at 1315 nm on the I(2P1/2) → I(2P3/2) transition of atomic iodine has been obtained by a near resonant energy transfer from O2(a1&Dgr;) produced using a low-pressure oxygen/helium/nitric-oxide discharge. In the electric discharge oxygen-iodine laser (ElectricOIL) the discharge production of …

Important kinetic effects in the hybrid ElectricOIL system

Joseph W. Zimmerman, Darren M. King, Andrew D. Palla, J. T. Verdeyen et autres

Laser action at 1315 nm on the I(2P1/2) → I(2P3/2) transition of atomic iodine has been obtained by a near resonant energy transfer from O2(a1Δ) produced using a low-pressure electric discharge. In the electric discharge oxygen-iodine laser (ElectricOIL) the discharge production of …

Plasma torches for the generation of atomic fluorine and nitrogen

Mike Read, Willi G. Schwarz, David B. Oakes, Alan H. Gelb et autres

Summary form only given. Several microwave-driven plasma torch are being developed for a number of applications. This technology, named "MIDJet," has no electrodes or dielectric containment vessel, instead relying on a strong vortex flow to confine the discharge. This allows operation at …

Measurements of Pressure-Broadening Coefficients for the F‘ = 3 ← F‘ ‘ = 4 Hyperfine Line of the 2P1/2 ← 2P3/2 Transition in Atomic Iodine

Steve J. Davis, Phillip A. Mulhall, M. Bachman, William J. Kessler et autres

We describe a series of measurements of pressure-broadening coefficients for the F‘ = 3 ← F‘ ‘ = 4 line of the 2 P 1/2 ← 2 P 3/2 transition in atomic iodine. This is the optical transition of the chemically pumped …

Energy Transfer Studies in Interhalogen Molecules

Steve J. Davis, Karl W. Holtzclaw, William J. Kessler, Lawrence G. Piper

This program is examining energy transfer processes in interhalogen molecules that have potential for visible chemical laser development. Spectrally resolved laser induced fluorescence is used to determine rotation-to-translation (R-T) and vibration-to-translation (V-T) rate coefficients. In this report we compare several fitting laws …

Tailoring of electron and hole energies in strained GaAsP/AlGaAs quantum wells using fluorine-impurity-induced layer disordering

Utpal Das, Steve J. Davis, Ramu V. Ramaswamy, Fred A. Stevie

Restoration or removal of the light- and heavy-hole degeneracy of the exciton transitions for light polarized parallel to the layers in strained GaAs0.91P0.09/Al0.3Ga0.7As single quantum wells has been demonstrated by fluorine-impurity-induced layer disordering. Disordering due to As and P interdiffusion has also …
