Owing to the sensing applications, titania nanoparticles (TNPs) are synthesized by sol-gel route at low temperature (80 °C). For pH sensing response, four different pH dyes (phenol red, bromophenol blue, cresol red, and phenolphthalein) mixture is immobilized within TNPs. Thermal and structural beha...
