• Amino acid-based DESs are cheap, green, biocompatible and biodegradable. Refractive index of amino is for the first time investigated Effect HBD, HBA, mole ratio, component temperature investigated. hydrogen-bonding donor, acceptor, components on refractive Results show that decreasing ratio donor to acceptor would decrease index. shows negatively linear correlation with temperature. This work expand application green optical device sustainable characterization.
