Solid solutions crystallize in the monoclinic crystal system (space group С2/с, Z = 4) and are members of a small family of inorganic compounds containing [Ge4O13]10– anions. The photoluminescence properties of germanates upon excitation by radiation with λex = 275 nm have been studied. The spectra of the compounds show a broad band with a maximum at 313 nm and a set of lines in the range of 525–730 nm, corresponding to intraconfigurational 4f–4f transitions in Gd3+ and Sm3+ ions. It has been found that germanate Ba2Gd1.95Sm0.05Ge4O13 has the maximum luminescence intensity. For this sample, the color characteristics and the temperature dependences of the intensity ratios of the main luminescence bands upon heating to 498 K have been studied. It has been concluded that Ba2Gd1.95Sm0.05Ge4O13 can be used as a material for non-contact temperature sensing and light emitting diodes.</p></abstract><trans-abstract xml:lang="ru"><p id="idm45181324135488">Тетрагерманаты Ba<sub>2</sub>Gd<sub>2 –</sub> <sub><italic>x</italic></sub>Sm<sub><italic>x</italic></sub>Ge<sub>4</sub>O<sub>13</sub> (<italic>x</italic> = 0.025–0.8) получены твердофазным методом.
