This paper presents comparative analysis of thermally (TL) and optically (OSL) stimulated luminescence of a number of lutetium orthosilicates (LSO) single crystals and single crystalline films. Samples under study were prepared with two techniques: Czochralski method for single crystals and liquid phase epitaxy method for single crystalline films. This work describes in particular similarities and differences in OSL and TL response for alpha and beta particles between samples with different crystal form. The emission spectrum of LSO was found to extend from 350?nm to 500?nm, with a maximum near 430?nm. Intensity of TL and OSL of some samples to beta radiation was found to be quite high, indicating a potential of LSO for applications in dosimetry.
