Photoluminescence: Fluorescence and Phosphorescence

Photoluminescence: Fluorescence and Phosphorescence

Photoluminescence is a process where a molecule absorbs light energy and re-emits it in the form of light. This phenomenon occurs when a substance absorbs photons, promoting its electrons to higher energy level excited states, followed by a relaxation process in which the electrons return to their original ground state energy levels and emit light. Photoluminescence is widely observed in various materials, including semiconductors, and organic and inorganic compounds.

Nuclear Overhauser Enhancement (NOE)

Nuclear Overhauser Enhancement (NOE)

Irradiation of a spin-active nucleus causes an increase or decrease in the signal intensity of neighboring nuclei that are not necessarily chemically bonded or involved in J-coupling. This phenomenon, called the nuclear Overhauser enhancement (NOE), results from through-space interactions between the nuclear spins. The NOE effect decreases with increasing internuclear distance and is generally not observed beyond 4 angstroms. In NOE, dipole-dipole interactions between neighboring spin-active...

Double Resonance Techniques: Overview

Double Resonance Techniques: Overview

Double resonance techniques in Nuclear Magnetic Resonance (NMR) spectroscopy involve the simultaneous application of two different frequencies or radiofrequency pulses to manipulate and observe two distinct nuclear spins. One important application of double resonance is spin decoupling, which selectively suppresses coupling with one type of nucleus while observing the NMR signal from another nucleus, simplifying the spectrum and enhancing resolution.
Spin decoupling is usually achieved by...

Deactivation Processes: Jablonski Diagram

Deactivation Processes: Jablonski Diagram

Luminescence, the emission of light by a substance that has absorbed energy, is a process that involves the interaction of molecules with light. The energy-level diagram, or Jablonski diagram, is a graphical representation of these interactions, illustrating the various states and transitions a molecule can undergo. In a typical Jablonski diagram, the lowest horizontal line represents the ground-state energy of the molecule, which is usually a singlet state. This state represents the energies...

Nuclear Transmutation

Nuclear Transmutation

Nuclear transmutation is the conversion of one nuclide into another. It can occur by the radioactive decay of a nucleus, or the reaction of a nucleus with another particle. The first manmade nucleus was produced in Ernest Rutherford’s laboratory in 1919 by a transmutation reaction, the bombardment of one type of nuclei with other nuclei or with neutrons. Rutherford bombarded nitrogen-14 atoms with high-speed α particles from a natural radioactive isotope of radium and observed protons being...

Background:

Generation of coherent vacuum ultraviolet (VUV) radiation is crucial for various spectroscopic and materials science applications.
Four-wave mixing (FWM) is a nonlinear optical process used to generate new frequencies, but efficiency can be limited.
Two-photon resonances can significantly enhance nonlinear optical processes by increasing the interaction probability.

Purpose of the Study:

To investigate the generation of coherent VUV radiation using four-wave mixing enhanced by two-photon resonances in xenon.
To determine the optimal conditions (e.g., xenon pressure) for maximizing VUV generation efficiency and output intensity.
To explore the potential for parametric generation at specific VUV wavelengths.

Main Methods:

Employed four-wave mixing (FWM) processes in xenon gas.
Utilized two-photon resonances to enhance the nonlinear interaction.
Varied xenon pressure to optimize phase-matching conditions and observed output intensities at specific VUV wavelengths (e.g., 125.9, 126.1, 125.4 nm).

Main Results:

Successfully generated coherent VUV radiation at wavelengths including 125.9, 126.1, and 125.4 nm.
Achieved maximum conversion efficiencies on the order of 10⁻⁴.
Observed maximum output intensities for difference frequency generation (2ω₁ - ω₂) at specific xenon pressures and phase mismatch values for different resonant states (7p[0 (1/2)](0), 7p[1 (1/2)](2), and 6p' [1 (1/2)](2)). Parametric generation at 117.0 nm via the 7s[1(1/2)](0)(1) state was also noted.

Conclusions:

Two-photon resonances significantly enhance four-wave mixing processes in xenon for VUV generation.
Optimizing xenon pressure is critical for achieving efficient VUV generation by controlling phase-matching conditions.
The demonstrated method provides a viable route for generating tunable coherent VUV radiation.
