Rare earth (La, Pr, Sm, Ce and Yb)-doped porous In 2 O 3 nanosheets are prepared by a solvothermal method. The effect of rare earth elements on the structure, morphologies and gas-sensing performance of In 2 O 3 nanosheets is systematically investigated. The mixed phase composed of c-In 2 O 3 and rh...
