- The results of the investigations of X-ray excitation spectra, thermostimulated luminescence and influence of light illumination on the thermoluminescence glow curves of $Eu^{3+}$-doped $Ca_{3-x}Cd_xGa_2Ge_3O_{12}$ garnet polycrystalline samples are presented. It is shown that $Ca_{3-x}Cd_xGa_2Ge_3O_{12}$ polycrystalline samples are characterized by intrinsic luminescence, which consists of several components. The nature of intrinsic luminescence is discussed. It is suggested that the nature of thermoluminescence glow peak near 150 K is connected with the $[(V_{Ge}+V_{O})^{-}-F^+]$ associations formed under X-ray irradiation at 85 K. The influence of light illumination on the TSL intensity of the preliminary X-ray irradiated samples is shown.
