Owing to the fast responsive fiber optical pH sensing characteristics, silica porous matrix is synthesized through a low temperature sol-gel technique. Three different pH dyes namely bromophenol blue (BPB), creosol red (CR) and phenol red (PR) are encapsulated in silica matrix to observe their behav...
