“…В работе [13] продемонстрирована генерация в порошках EuАl 3 (BO 3 ) 4 и предложено использовать этот материал для разработки систем визуальной информации повышенной яркости. В настоящее время многие исследовательские группы работают над созданием лазеров и люминофоров на основе YAl-и GdAl-боратов, легированных различными РЗ и d-ионами [14][15][16][17]. Нелегированные кристаллы YAl-боратов оказались эффективной средой для генерации четвертой гармоники неодимового лазера (266 nm) [18].…”

Luminescence spectra of single crystals of rare-earth gallium borates LnGa_3(BO_3)_4 (Ln = Nd, Sm, Tb, Er, Dy, or Ho) at room (300 K) and cryogenic (10 K) temperatures are presented for the first time. Photoluminescence has been recorded in the wavelength range of 470–5000 nm (2000–21 300 cm^–1) with a high spectral resolution (down to 0.1 cm^–1) upon excitation by different diode lasers. The spectra obtained cannot be unambiguously interpreted within one luminescent center, which can be due to the presence of defects and/or inclusions of other crystalline phases. The optical nonlinearity of rare-earth–gallium borates has been estimated using the Kurtz–Perry powder technique. The typical intensities of the second-harmonic generation in gallium borate powders are 30–40 (with respect to quartz), and the optical nonlinearity is as good as the nonlinearity of the efficient rare-earth aluminum borate YAl_3(BO_3)_4.
