Theoretical extinction coefficient
WebbThe calculated concentration, assuming the stated extinction coefficient value, is as follows: (A / εpercent) × 0.1 = cmg/ml (0.016 / 160) × 0.1 = 1 mg/L The molar extinction coefficient at 449 nm for fucoxanthin in ethanol is approximately 160 L/g/cm. Using ChromaDex Standards WebbThis might be because in SQ limit absorptivity is considered Heaviside function while in SLME absorptivity of the material takes both its absorption coefficient and thickness into consideration. Due to detailed framework of SLME, efficiency of perovskites predicted using this approach is higher as the thickness of perovskites increases compared to that …
