The properties of PVA and starch polymer mixes doped with Rhodamine-B are the subject of this study., which has a weight-to-weight ratio of 1:1. PVA and starch polymer mixes with varying glycerin ratios of 0, 25, 30, 35, and 40% wt. Different percentages of the polymer mixture consisting of sarch/PVA with 30% wt/wt of glycerine) were doped with rhodamine dye (0,1,2,3,5). Samples were then analyzed using FTIR, which revealed active groups as well as a clear association between the materials used, Optical spectrum was also measured for the (300-900 nm) range, Optical characteristics of the combination, such as absorbance, absorption coefficient(α), optical energy gap(Eg) and Extinction Coefficient(K), have been researched.
