Photo-patternable optical chemical sensors based on hybrid sol-gel materials

work was a UV-pattemable sol-gel prepara- tion which was developed to produce integrated optic components for telecom applications [6]. The sol-gel precursors used in that prepara- tion were 3-(trimethaxysilyl)-propylmethacrjlate and zircaniumprap- oxide. Methacrylic acid was added to complex the zirconium precursor. The photoinitiator used for the radical polymerisation was Irgacure
