The optical properties of lanthanum nickelate (LNO) films grown by chemical solution decomposition on sapphire substrates were measured and extracted. The relatively low imaginary part of the dielectric function indicates that LNO may perform well in plasmonic applications at traditional telecommunication frequencies.
