Abstract
Herein, solvents i.e., methanol, ethanol, propanol, and butanol-assisted titania nanoparticles (TNPs) are synthesized by low-temperature sol-gel method for pH sensing applications. The influence of solvent on the morphology, roughness, porosity, refractive index, and sensing properties are investigated. The relatively high average roughness 2.5 nm and lower refractive index 1.69 is observed for B-TNPs. The sensitivity of butanol-assisted phenol red encapsulated TNPs is observed 2.32 counts/pH.
