Glass ceramics doped with neodymium oxide (100–x)10(20BiO–60BO–20BaO)–90YAG:xNdO (x = 0.1, 0.5, 1, 1.5 and 2 mol.%) from an ultrafine charge, according to the conditions for obtaining which its particles (with an average size of 1 micron) consist of a core and shell, which, when sintered, form crystals and the glass phase that holds them together. With the indicated compositions of the glass phase and the crystalline component and their ratio in the charge precursor, which is unique in structure, glass-ceramic samples were formed using a laser, in which the presence of glass was confirmed by the DSC method, and the garnet phase was determined by the XRD method against the background of a halo from the glass phase. The physicochemical and spectral luminescent characteristics of the obtained glass ceramic samples have been studied, while the maximum luminescence at 1060 ± 3 nm is reached at 1.5 mol.% NdO, and a further increase of 2 or more mol.% leads to a decrease in the luminescence peak due to the effect of concentration quenching.
