Fig. 3

a Dose-dependent lasing spectra (only showing the CWL) of DG and R6G displaying wavelength blue-shift of DG and red-shift of R6G with increase of R6G concentration. b Mean wavelength-concentration plot of DG (green) and R6G (pink) of five experiments. Data are presented as mean values ± SD (n = 5). c log-scale Δλ-concentration curve showing that the wavelength gap (Δλ) exponentially increases as the R6G concentration increases (for a mathematical model ref. SI table S3, Δλ = λ2(R6G)-λ1(DG)). Data are presented as mean values ± SD (n = 5).
