Annotation The paper describes the synthesis of Ce3 +-doped terbium aluminum garnet (TAG) phosphors with use of nanostructured oxides of aluminum and rare earths. Aluminum oxide nanoparticles were obtained by gaseous-disperse synthesis and characterized by X-ray diffraction, differential thermal analysis and scanning electron microscopy. It was shown that the Ce3 + ions in TAG exhibit the intense broad band emission with a maximum at about 563 nm and the quantum efficiency of luminescence of the Тb3(1 – x)Ce3xAl5O12 (х = 0.03) phosphor was found as high as 0.83.
