Abstract

We research light emission properties of the optical gain medium based on biopolymer for biocompatible laser system. The deoxyribonucleic acid-cetyltrimethylammonium chloride surfactant (DNA-CTMA) doped with riboflavin has been measured by UV-vis spectroscopy and confirmed by photoluminescence measurement for the five different composition doping rates (100-2000 ppm of riboflavin) of the blended solution with hexafluoro-2-propanol (HFIP). The riboflavin-doped DNA-CTMA:HFIP solid-state thin-films are achieved by spin-coating method and the doping behavior has been studied by Raman spectroscopy.
