Abstract	Glassy-crystalline samples of compositions (B$_{2}$O$_{3}$-Al$_{2}$O$_{3}$-SiO$_{2}$):Eu$^{2+}$ (3 at %) and (B$_{2}$O$_{3}$-2SiO$_{2}$):Eu$^{2+}$ (3 at %) were obtained by sintering the initial powdered mixtures at 1300°C in air. Being excited by laser radiation at a wavelength of 325 nm, the former samples exhibit intense blue photoluminescence with a maximum at 434–448 nm, while the latter samples emit in the violet spectral interval with a maximum at 409 nm. An increase in the content of B$_{2}$O$_{3}$ leads to a shift of the emission maximum toward a shorter wavelength, while additional annealing at 1300°C C in vacuum shifts the spectrum toward longer wavelengths.
