1. A process of making a gold nanorod J-aggregate, said process comprising:
a) combining;
(i) a first solution comprising a solvent selected from the group consisting of 1-methylpyrrolidinone, N,N-dimethylacetamide, N,N-dimethylformamide, tetrahydrofuran, dichloromethane, chloroform, 1,4-dioxine and a mixtures thereof; and gold nanorods; and
(ii) a second solution comprising a solvent selected from the group consisting of 1-methylpyrrolidinone, N,N-dimethylacetamide, propylene carbonate, tetrahydrofuran, 1,4-dioxine, ethyl acetate, acetone, dichloromethane, chloroform, ethanol, methanol, isopropanol and mixtures thereof and one or more polyimides,
said one or more polyimides having a solubility of at least 5 g/L at 25° C. at 1 atmosphere of pressure in said first solution's solvent and said second solution's solvent;
said first solution and said second solution being combined in a ratio of from 0.1:1 to about to about 10:1; said first solution having a concentration of gold nanorods of from about 0.01 nM to about 10 nM and said second solution having a concentration of polyimide of from about 0.1 g/L to about 1000 g/L;

b) combining:
(i) a solution comprising a solvent, said solvent being selected from the group consisting of 1-methylpyrrolidinone, N,N-dimethylacetamide, N,N-dimethylformamide, tetrahydrofuran, dichloromethane, chloroform, 1,4-dioxine and mixtures thereof, gold nanorods and one or more polyimides; and
(ii) a second solvent selected from the group consisting of 1-methylpyrrolidinone, N,N-dimethylacetamide, propylene carbonate, tetrahydrofuran, 1,4-dioxine, ethyl acetate, acetone, dichloromethane, chloroform, ethanol, methanol, isopropanol and mixtures thereof;
said one or more polyimides having a solubility of at least 5 g/L at 25° C. at 1 atmosphere of pressure in said solution's solvent and said second solvent;
said solution and said second solvent being combined in a ratio of from 0.1:1 about to about 10:1; said solution having a concentration of gold nanorods of from about 0.01 nM to about 10 nM and a concentration of polyimide of from about 0.1 g/L to about 1000 g/L; or

c) combining:
(i) a first solution comprising a solvent and gold nanorods, said solvent being selected from the group consisting of 1-methylpyrrolidinone, N,N-dimethylacetamide, propylene carbonate, tetrahydrofuran, 1,4-dioxine, ethyl acetate, acetone, dichloromethane, chloroform, ethanol, methanol, isopropanol and mixtures thereof, and
(ii) a second solution comprising a solvent selected from the group consisting of 1-methylpyrrolidinone, N,N-dimethylacetamide, tetrahydrofuran, dichloromethane, chloroform, 1,4-dioxine and mixtures thereof and one or more polyimides;
said one or more polyimides having a solubility of at least 5 g/L at 25° C. at 1 atmosphere of pressure in said first solution's solvent and said second solution's solvent;
said first solution and said second solution being combined in a ratio of from 0.01:1 about to about 10:1, said first solution having a concentration of gold nanorods of from about 0.01 nM to about 10 nM and said second solution having a concentration of polyimide of from about 0.1 g/L to about 1000 g/L.
