Highly porous thin films obtained by spray-gel technique
(Lima (Perú)PE, 2004-08)Acceso abiertoCombining the spray pyrolysis and the sol-gel techniques (spray-gel) gives the possibility to produce very rough and highly diffuse films, under appropriate conditions. This technique is suitable for producing multifunctional ... -
Highly porous tungsten-oxide-based films obtained by spray-gel for gas sensing applications
(Lima (Perú)PE, 2005-08)Acceso abiertoHighly porous mixed WO3–SnO2 films have been prepared from an aqueous solution of SnCl4.5H2O and polytungsten gel with a molar ratio of Sn/W from 0 to 1. These solutions were sprayed on to alumina substrates at 220 ºC. The ... -
Infrared absorption in Li-intercalated tungsten oxide
(Lima (Perú)PE, 2007-08)Acceso abiertoThin films of amorphous and polycrystalline tungsten oxide, were produced by reactive dc magnetron sputtering and nanocrystalline films were deposited by advanced gas evaporation. The films were submitted to electrochemical ... -
Surface morphology engineering of metal-oxide films by chemical spray pyrolysis
(Lima (Perú)PE, 2007-08)Acceso abiertoChemical Spray Pyrolysis Technique and a combination of sol-gel and spray pyrolysis techniques have been used in order to monitor the morphology of metal-oxide-based thin films to be used as functional materials. We can ...
