1. A method of making a smart optical material (SOM), comprising:
mixing polypropylene in a solvent to form a first solution;
mixing a zinc salt in 2-hydroxyethyl methacrylate and heating to form a second solution;
mixing rhodamine B and a peroxide into the second solution to form a third solution;
mixing the third solution into the first solution to form a reaction solution, wherein the peroxide initiates polymerization of the 2-hydroxyethyl methacrylate to form poly(2-hydroxyethyl methacrylate); and
separating the SOM from the reaction solution,
wherein the SOM has at least two bandgaps,
wherein a first bandgap is from 1.4-1.5 eV, and
wherein a second bandgap is from 1.8-1.9 eV.
