As a result, the coupled radio frequency power has been combined with a diminished spectral broadening, resulting in current drive in the plasma core.
This additional transition significantly modifies the PL line shape at higher temperatures (Fig. 2) and introduces additional PL band broadening resulting in a significant deviation of the calculated temperature dependences from measured temperature dependences of FWHM and PL Emax within the temperature range 150 300 K (Fig. 3a, 3b).
The HWHM is in the range of 15°, compared to a full width of 0.15° in the radial direction, the latter reflecting instrumental broadening (resulting from beam divergence and detector point spread) and grain-size related broadening (in nanoparticles, crystallite size correlates inversely with peak width).
The D + D′ bands are broadened resulting in a sharp curve in the 2D region.
Coincidence Doppler broadening results indicate increase in specific volume in the crystalline region of the polymer.
It is known that peak broadening results from both finite crystallite size and strain effect within the crystal lattice [29].
The linewidth is also distorted by the high-energy tail, indicating that the spectral broadening results mostly from the thermal broadening.
The increase in non-radiative recombination process due to the inhomogeneous broadening results in a decrease in the PL intensity with an increase in ablation time.
The average crystallite size of the NPs obtained using XRD peak broadening results and the Debye-Scherrer formula was 25.62 nm, and the value of strain in NPs was found to be 0.0015.
Other studies have proposed that spike broadening results from cumulative inactivation of several potassium (K+) channels, including large-conductance (BK-type) Ca2+-dependent K+ channels [40], voltage-gated delayed rectifier K+ channels [41], and voltage-gated A-type K+ channels [42].
