The effect of coupled substitution of Zr4+/Ga3+ for In3+ in In2O3 upon the structural, electrical and optical properties has been studied. The In2-2xGaxZrxO3 solid solution with bixbyite structure has been synthesized for 0 ≤ x < 0.15. A decrease in resistivity for the composition x = 0.025 (ρRT = 5.5x10-3 Ω.cm) by approximately one order of magnitude if compared to In2O3 (ρRT = 2.2x10-2 Ω.cm) was obtained. The maximum percent reflectance around 500 nm is lowered by 15% with respect to pure In2O3. These novel oxides show their potential as transparent conductors.
