(a) Normalised room temperature PL spectra for Set C samples (b) PL intensity versus Bi content at room temperature with P e = 320 Wcm−2.
(a) Temperature dependent of PL peak energy of Set C samples and (b) FWHM measured at 10 K when excited with P e = 53 Wcm−2. The dashed lines are fitting using Varshni equation.
