Abstract
Fluorescence based optical sensors has become an attraction in many areas, including industrial, biomedical and environmental applications. Optical sensor developed for water quality monitoring such as dissolved oxygen sensor becomes important such as monitoring the health of aquaculture environment. This optical DO sensor use oxygen quenching luminophore as the sensor material. In this work, the performance of tris(4,7-diphenyl-1,10 phenanthroline)ruthenium(II) ([Ru(dpp)3]2+) was investigated through the thin films morphology and their luminescence spectral profile. The Scanning Electron Microscopy (SEM) images result indicates that ([Ru(dpp)3]2+) doped Octyl-triEOS/TEOS/Triton x-100 composites form uniform thin film and reduce cracks, likely to produce a reliable luminophore sensor. In addition, the spectral profile for 3 different ([Ru(dpp)3]2+) concentration were observed using high-resolution UV-VIS Spectrometer. The emission wavelength for all the samples have the same peak which seen at 610 ± 4 nm. The emission intensity shows an increasing pattern proportional to the concentration of ([Ru(dpp)3]2+). These experimental result demonstrates the ([Ru(dpp)3]2+) sol-gel thin film potentially be used for Dissolved Oxygen (DO) optical sensor luminophore.
