We grew InGaN/GaN MQW structure on Ga₂O₃/GaN template substrate and GaN substrate and investigated their optical properties. Photoluminescence (PL) and time-resolved PL measurements indicates no difference due to the kind of substrates, suggesting that the optical properties of InGaN/GaN MQW on the Ga₂O₃/GaN template substrate are quite similar to those on the GaN substrates.
