Diseño y construcción de un sistema para la supervisión in-situ del crecimiento de una película delgada de ZnO fabricada por rociado pirolítico
(Lima (Perú), 2005-08)
Se implementó un sistema que supervisa in-situ el espesor y calcula el perfil de una película delgada fabricada por la técnica de rociado pirolítico. El sistema se basa en la medición de la reflexión de un haz láser que ...
Surface morphology engineering of metal-oxide films by chemical spray pyrolysis
(Lima (Perú), 2007-08)
Chemical 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 ...
Synthesis and characterization of rough electrochromic phosphotungstic acid films obtained by spray-gel process
(Lima (Perú), 2003-07)
Rough electrochromic phosphotungstic acid (PWA) films were fabricated by spraying a gel of phosphotungstate anions with a molar ratio of P:W = 1:12 onto glass substrates precoated with transparent and electrically conducting ...
The influence of the ethanol/water molar ratio in the precursor solution on morphology and photocatalytic activity of pyrolytic ZnO films
(Lima (Perú), 2005-08)
Zinc oxide films were fabricated by a home made spray pyrolysis system equipped with an optical set-up ensuring the in-situ control of the film growth. 0.1 M of zinc acetate diluted in a mixture of ethanol and water was ...
Highly porous thin films obtained by spray-gel technique
(Lima (Perú), 2004-08)
Combining 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 ...
Spray pyrolysis deposited zinc oxide films for photo-electrocatalytic degradation of methyl orange: influence of the pH
(Lima (Perú), 2003-07)
Zinc oxide films were made by spray pyrolysis equipped with an optical system for in-situ thickness measurement; zinc acetate water solution was used as spraying solution. The pH of the spraying solution was modified in ...
