Abstract

Indium vanadate (InVO4) nanoribbons were irradiated with various doses of gamma ray irradiation. The results revealed that the crystal structure remained unchanged after irradiation while the UV–Vis spectra underwent a red-shift with increasing irradiation dose. In addition, gamma ray irradiation enhanced the sensibility of InVO4-based sensors for ammonia testing. The improved properties of InVO4-nanobased sensors exposed to irradiation might be ascribed to the defects introduced by gamma ray, making gamma ray irradiation a good approach for material modification.
