   Люминофоры Na2Al2B2O7, легированные Dy3+ и Sm3+, синтезированы при 850 °C в течение 6 ч на воздухе. Фазовый анализ всех полученных боратов проводился методом порошковой рентгеновской дифракции (РФА). С помощью спектрофлуориметра при комнатной температуре исследованы фотолюминесцентные свойства полученных люминофоров. При λвозб = 350 нм Na2Al2B2O7:Dy3+ излучает при длинах волн 481–491, 575–583 и 673 нм, при λвозб = 402 нм Na2Al2B2O7:Sm3+ излучает на длинах волн 561, 603, 650 и 709 нм.

   Dy3+ and Sm3+-doped Na2Al2B2O7 phosphors were synthesized at 850 ºC for 6 h in air. The phase analyses of all prepared borates were carried out using powder X-ray diffraction (XRD). A spectrofluorometer was used to examine the photoluminescence (PL) characteristics of the prepared phosphors at room temperature. When excited at 350 nm, Na2Al2B2O7:Dy3+ radiates at 481–491, 575–583, and 673 nm. After being excited at 402 nm, Na2Al2B2O7:Sm3+ radiates at 561, 603, 650, and 709 nm. As a result of this study, two new optical materials that emit light in the visible region were prepared.
