    摘要： A method of fabricating a multi-layered thin film electrochemical device is provided. The method comprises: providing a first target material in a chamber; providing a substrate in the chamber; emitting a first intermittent laser beam directed at the first target material to generate a first plasma, wherein each pulse of the first intermittent laser beam has a pulse duration of about 20 fs to about 500 ps; depositing the first plasma on the substrate to form a first thin film; providing a second target material in the chamber; emitting a second intermittent laser beam directed at the second target material to generate a second plasma, wherein each pulse of the second intermittent laser beam has a pulse duration of about 20 fs to about 500 ps; and depositing the second plasma on or above the first thin film to form a second thin film.

    摘要： Various embodiments include a method of producing chemically pure and stably dispersed metal and metal-alloy nanoparticle colloids with ultrafast pulsed laser ablation. A method comprises irradiating a metal or metal alloy target submerged in a liquid with ultrashort laser pulses at a high repetition rate, cooling a portion of the liquid that includes an irradiated region, and collecting nanoparticles produced with the laser irradiation and liquid cooling. The method may be implemented with a high repetition rate ultrafast pulsed laser source, an optical system for focusing and moving the pulsed laser beams, a metal or metal alloy target submerged in a liquid, and a liquid circulating system to cool the laser focal volume and collect the nanoparticle products. By controlling various laser parameters, and with optional liquid flow movement, the method provides stable colloids of dispersed metal and metal-alloy nanoparticles. In various embodiments additional stabilizing chemical agents are not required.
