Further increase in the transmission distance is attributed to the pulse broadening due to the dispersion.
All the above results confirm that the broad halo diffracted peak in the milled MgCu sample is attributed to the overlap of the broadened peaks of the very small Mg2Cu and Cu nanocrystalline phase, not the MgCu amorphous phase.
Based on the above analysis, it is concluded that the long-time milled MgCu sample consisted of Cu and Mg2Cu nanocrystals, and the halo peak in the XRD pattern of the 18-h milled sample ought to be attributed to the overlap of the broadened peaks of the Cu and Mg2Cu nanocrytals.
This is attributed to the higher value of HRS and broadened memory window.
Efficient pure red emission with suppressed efficiency roll-off was obtained attributed to the reduction of accumulation holes, the broadening of recombination zone, and the improved balance of holes and electrons on Eu TTA 3phen molecules.
And the increase in fundamental resonance broadening is attributed to the reduced effective inductance.This proposed structure provides a meaningful way toward expanding the fundamental mode operating range from narrowband to broadband with a tunable behavior.
As the milling time increases, the intensities of Mg, Mg2Cu, and Cu peaks gradually decrease, and the corresponding widths broaden, which is mainly attributed to the grain refinement and accumulation of microstrain during the ball milling.
Peaks related to high angles have submerged in the background due to the large line broadening, which is attributed to the nanoscale size of the particles.
Many researchers have claimed that nanowires with different morphology than the bulk produce band gap broadening, which is attributed to the wide absorption spectrum and optical transmission range.
This λ max shift to a larger value and the excessive broadening can be attributed to the increased crystallite size of the nanoparticles due to particle aggregation which decreases the sensitivity to plasmon response [5].
