Abstract: The present disclosure provides methods of applying a filtering coating to a substrate, comprising: depositing a solution on a surface of a substrate, wherein the solution comprises an organic solvent with nanorods dispersed within the solvent. Evaporation of the solution is allowed and/or controlled to increase a volume fraction of the nanorods in the solution as a function of the evaporation. Thus, an aligned deposit of the nanorods is provided as a function of the evaporation, wherein the aligned deposit of nanorods includes at least thousands of the nanorods with at least a majority of the nanorods aligned relative to a length of the nanorods.
