Near-normal incidence infrared reflectivity spectra of (001) strontium lanthanum aluminate (SrLaAlO[sub 4]) single crystal have been measured under different temperatures in the frequency region between 100 and 6500 cm-1. Five phonon modes are distinguished at low frequency while no spectral features were observed above 1000 cm-1. All the reflectivity spectra are fitted with the factorized form of the dielectric function. The dielectric properties of the SrLaAlO[sub 4] crystal in far-infrared region are presented and analyzed. © 2004 American Institute of Physics. [ABSTRACT FROM AUTHOR]
