Assuming a spherical shape and a cubic lattice, the Scherrer formula (D = 6.96/FWHM) can be used to estimate the diameter of the crystallites as D = 75.3 ± 30.0 nm for decomposition at 11.5 GPa and D = 34.6 ± 8.4 nm for decomposition at 29.0 GPa22....
The crystallite size obtained from GIXS measurements is estimated by the Scherrer formula given by, where τ is the crystal grain size, κ is a constant (0.94), λ is the wavelength (1.24 Å), θ is half the angle corresponding to the intensity peak and β is the FWHM of the ...

it is highly believed that the Pb2+ions were fully incorporated into the host matrix. The results suggest that varying the mol% of Pb2+ions does not affect the crystal structure of the phosphor. The crystallites sizes were estimated by using the Scherrer formula [21], using the most intens...
In general, the crystalline size (L) of the terpolymers can be estimated by the Scherrer formula [15],(1)L=0.9λ/(Bcosθ),where λ is the x-ray wavelength, B is the full width at half the maximum of the peak, and θ is the Bragg angle. The average crystalline sizes are then ...
The grain size was deduced from the width of the XRD peaks using the Scherrer formula and was found to decrease with the addition of silver. The chemical and phase composition was determined from XPS measurements. The optical constants were measured using spectroscopicellipsometry. A correlation ...

(Supplementary Fig.4) confirm the formation of the pure wurtzite-structure GaN. Based on the Scherrer’s formula and the (110) diffraction, the crystal size of the synthesized GaN samples is determined to be 7.4, 10.5, and 16.7 nm, respectively (Supplementary Table2). Hereafter, the ...
The mean crystallite size,{D}_{m}of the as-produced samples for comparing the size structure was calculated using FWHM of all peaks via the Scherer equation40,41. Based on the Scherrer equation,{D}_{m}(in nm) is inversely correlated to the peak width β (FWHM) via the following relat...
