The spectral and kinetic luminescence characteristics of undoped Ca₃Ga₂Ge₄O₁₄ single crystals have been studied using synchrotron irradiation with 4-30 eV energy, X-ray and optical irradiation (N₂ laser) in 10-300 K temperature range. It is established that the undoped crystals show an intrinsic lum...
