WebJan 19, 2024 · As it is known, the FWHM of PL band of PS sample traduces the gap distribution and its intensity is related to carrier’s population . The FWHM of PL band for different temperatures of Ni–PS sample are higher than those of the PS. This is due to the contribution of various populations processes that differ from the Si nanocrystallites (nc-Si).

WebJun 7, 2024 · We further observed that the PL FWHM narrowed from 24 nm to 18 nm after introducing MABr. This indicates that the MABr additive has improved the sharpness of the perovskite band edge. In a distribution, full width at half maximum (FWHM) is the difference between the two values of the independent variable at which the dependent variable is equal to half of its maximum value. In other words, it is the width of a spectrum curve measured between those points on the y-axis which are half the maximum amplitude. Half width at half maximum (HWHM) is half of the FWH…
WebThe FWHM increases with a decreasing d. A decrease of FWHM with a decreasing d is seen in the region where the number of vertically connected islands increases. We observed a very sharp PL peak for a 3-layer stacked structure, which is attributable to an extremely reduced island height fluctuation as well as vertical coupling. WebApr 3, 2024 · The room temperature steady-state PL of MR-D1 and MR-D2 are narrowband and show peak emission, λ PL, at 485 and 488 nm and FWHM of 21 and 23 nm, respectively. The red-shifted emission of MR-D2 compared to MR-D1 is consistent with the smaller HOMO-LUMO gap observed in the electrochemistry.
