dc.description.abstract | El presente artículo realiza un análisis espectral de un conjunto de ensayos efectuados sobre una reacción foto catalítica modelo basada en la actividad de fenol disuelto en agua con oxido de titanio dopado como catalizador e irradiada con un haz de luz coherente, cuyo frente de onda corresponde a la superposición de dos vórtices ópticos con momento angular orbital entero definido de sentido opuesto. Como primera instancia se describe la arquitectura opto electro-química empleada en el estudio, luego se selecciona por medio de un barrido discreto de haces propagados de 405 y 450 nm, la longitud de onda adecuada para proyectar los vórtices ópticos sobre la muestra. Por último se realiza el tratamiento y análisis de las señales adquiridas a través de espectrofotometría UV de las muestras irradiadas con las distribuciones espaciales de luz de interés controladas por un holograma generado por computador. | spa |
dc.description.abstract | This paper presents a spectral analysis of tests performed on a photocatalytic model reaction based on phenol activity diluted in water with doped titanium oxide using as catalyst and irradiated with a coherent beam of light, whose wave front is the superposition of the optical vortices with integer orbital angular momentum opposite. Primarily, the architecture of the system optoelectronics and chemistry related is described, then is selected by discrete test of beams propagated the appropriate wavelength (405 and 450 nm) to project optical vortices over the sample. Finally, the processing and analysis of the signals acquired by a spectrophotometry UV, corresponding to the samples irradiated with the controlled spatial distributions of light by hologram generated computer. | eng |
