Both specific gravity and refractive index are affected by temperature, although the former is affected much less catastrophically. WebFluorescein (Ф=0.792) is used as the reference fluorophore for determination of quantum yield of C-Green. As a standard measurement, the quinine sulfate was dissolved in 0.1 M H2SO4 (refractive index (η) =1.33) and the fluorescein was dissolved 0.1 M NaOH (η =1.33). C-dots were dispersed in deionized water (η =1.33).
