Solar-blind photodetectors are designed from individual In2Ge2O7 nanobelts using a standard photolithography technique. The detectors demonstrated high sensitivity and selectivity towards the solar-blind spectrum, fast response and decay times ∼ 3 ms, high responsivity ∼ 3.9 × 10^5 A W^−1, and high quantum efficiency ∼2.0 × 10^8%.
