Thermal aqueous solution approach for the synthesis of triangular and hexagonal gold nanoplates with three different size ranges

Gold nanoplates with three different ranges of sizes from tens of nanometers to a few microns in width are prepared using a simple thermal reduction approach with cetyltrimethylammonium bromide surfactant in aqueous solution. The nanoplates are formed in relatively short periods of time, compared to the hours or days of time required in some room-temperature nanoplate preparation procedures.
