Figure 4.

Temperature dependence of experimental and fitted results of FWHM. The solid circles indicate the experimental FWHM extracted from the emission spectra in Figure 3. The solid black line represents the fit according to Equation 1. The colored lines represent the contributions to the FWHM from the inhomogeneous linewidth broadening (Inhom.) and interactions with LO phonons (LO) and impurities (Imp.).
