potassium oxide plasma - Opis:
- In this work, a spectroscopic research on laser-produced potassium oxide plasma using optical emission spectroscopy (OES) technology is provided. Laser-induced K2O plasma produced at various laser energy has also been defined by visible emission spectroscopy. Plasma is created by a solid potassium oxide object radiated by a pulsed laser in a room environment. A Nd:YAG laser pulse 9 ns in duration with wavelength of (532) nm and a focal length of (10) cm in the range of energy (300-700) mJ is used to generate plasma from a planar K2O sample. The electron temperature (Te) was calculated in ratio line intensities method, while the electron density (ne) was calculated using Saha-Boltzmann equation, also another plasma parameters was calculated such as plasma (fp), Debye length (λD) and Debye number (ND). The increase in electron temperature and density was observed as a function of laser energies. Measurement of the production of the electron temperature in the rang (0.996-1.202) eV, While the electron density is in the rang (1.8×1016-8.8×1016) cm-3.
