Development of dissolved oxygen optical fiber sensor using an organically modified silicate (ORMOSIL) / Zulkifli Mahmud

An organically modified silicate (ORMOSIL) sol-gel technique has been proven can enhance the luminescence of dissolved oxygen (DO) optical fiber sensor. The npropyltriethoxysilane (n-propyl-triEOS) and ruthenium are selected as an organic modifier. The absorption spectrum of the sensitive dyes of ru...

The absorption spectrum of the sensitive dyes of ruthenium, platinum and palladium are reflect to emission intensity of the dyes. Sol-gel fabrication parameters such as solvent, catalyst, and dye concentration are varied in order to investigate the effect on fluorescence emission intensity of the DO optical fiber sensor.
