Laser Ablation Method for Organic Nanoparticles

摘要: In recent years, studies of organic nanoparticles consisting aromatic and dye molecules have gradually been increasing [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13], as it is expected that can be used sensors, bioprobes, devices, so on. It fascinating to design electronic optical properties nanoparticles, synthesize component molecules, prepare their for realizing properties. We consider essential important establish how at the present stage investigation, indeed about half published deal with preparation methods 7]. Until now two approaches proposed applied based on deposition reprecipitation molecules. method, are evaporated in a chamber under vacuum [1] inert gas atmosphere [2], nm-sized aggregates deposited substrate. solution added poor solvent [3] without [4, 7] surfactant, precipitates molecule produced (see Chap. 2). Although these interesting useful, there an urgent need develop simpler more versatile nanoparticles. Recently, we laser ablation technique where some phthalocyanines hydrocarbons were adopted first example [8].
