In this study, we developed PhC ion sensor which structure is polymer for ion sensing filled in TiO₂ dot array. This ion sensor has an ability of fluorescent enhancement at blue. When this ion sensor immersed of K⁺ contained solution, this ion sensor change their fluorescence drastically. Fluorescence change value of this PhC ion sensor was 7 times larger than conventional ion sensor.
