Ba2NaNb5O15 (BNN) thin films were formed on sapphire (0001) substrates and magnesium oxide substrates using electron cyclotron resonance plasma sputtering. The BNN films were 7.2-8.4 μm thick and had atomic ratio compositions of Ba=2.0-2.1/5Nb and Na=0.9-1.1/5Nb. The films had no cracks. Single-phase BNN and (001)-oriented BNN films on sapphire (0001) were obtained at 823 K and 923 K. An in-plane-oriented BNN film on sapphire (0001) was formed at 923 K. The films were transparent and had the ability of second harmonic generation. The films on magnesium oxide (100) were also single-phase BNN, and (001)-oriented BNN films were obtained at 823 K, 873 K, and 923 K. An in-plane-oriented BNN film on magnesium oxide (100) was formed at 823 K. The films were transparent.
