Rojas Física, Astronomía y Matemáticas PVP polymers sub micronized particles Laser ablation in liquids Pulsed laser ablation of Silver and Gold targets, immersed in a polymeric solution of Polyvinylpyrrolidone (PVP), is used to generatecolloids and composite metal-polymer. Solutions of PVP in deionized water at different concentrations are employed. Two PVP numberaverage molecular weights were considered, 10000 g/mol and 55000 g/mol. The high purity targets are irradiated between 20 min and40 min with the third harmonic (THG) (∏= 335nm) of a Nd:YAG laser operating at a rate of 10 Hz with pulses of 8 ns. Opticalspectroscopy in UV and vis regions, Scanning Electron Microscopy (SEM), High Resolution Scanning Electron Microscopy (HR-SEM) andX-Ray are used to identify and determine the shape and size of the produced particles. Very stable sub-micrometric spherical particles forAu/PVP y Ag/PVP samples are obtained with diameters of 0.72πm y 0.40πm, respectively. The preparation of colloids is performed in onestep and no surfactant or dispersing agent is used in this process. 2016 artículo científico 0035-001X https://www.redalyc.org/articulo.oa?id=57045452001 en http://www.redalyc.org/revista.oa?id=570 Revista Mexicana de Física application/pdf Sociedad Mexicana de Física A.C.
