Abstract. Excitation and emission spectra under UV and X-ray excitations, as well as the luminescence decay kinetics of Gd3Ga5O12: Bi single crystalline films were studied. The emission spectra observed in the spectral region 350-700 nm at room temperature consist two elementary bands peaked at 446 and 521 nm. The influence of growth conditions on the luminescent properties of Gd3Ga5O12: Bi3+ garnet have been revealed. The integral and relative intensities of the luminescence bands depend on the excitation wavelength. The Bi3+ decay curves of all investigated films show non-single exponential behavior at room temperature.
