Abstract: Crystals of lutetium gadolinium garnet solid solutions (Lu$_{1-x}$Gd$_x$)Al$_5$O$_{12}$ (0 $\le x\le$ 0.6) doped with Ce$^{3+}$ and Pr$^{3+}$ ions have been prepared by the horizontal directional crystallization method, and their optical and luminescence properties have been investigated. It has been established that the introduction of gadolinium into the lutetium garnet lattice leads to a decrease in the antisite luminescence (Lu$_{\mathrm{Al}}$ centers) in the UV spectral range and to sensitization of the Ce$^{3+}$ ion luminescence. By contrast, the presence of gadolinium results in the quenching of the Pr$^{3+}$ luminescence due to the nonradiative excitation transfer from Pr$^{3+}$ ions to Gd$^{3+}$ ions.
