文摘

This paper reports the gel combustion synthesis of La _x Gd_{14-em class="EmphasisTypeItalic ">x} Ge₂B₆O₃₄ (x = 3 and 4) germanate borates codoped with Yb3+–Er3+ and Yb3+–Tm3+ active ions. The synthesized compounds are isostructural with Gd₁₄Ge₂B₆O₃₄ and crystallize in trigonal symmetry (sp. gr. P3₁). We have determined the unit-cell parameters of the synthesized mixed-cation germanate borates La₃Gd_9.74Yb_0.84Tm_0.42Ge₂B₆O₃₄ (a = b = 9.794 ?, c = 25.7913 ?, V = 2143 ?3) and La_3.16Gd₁₀Yb_0.7Er_0.14Ge₂B₆O₃₄ (a = b = 9.746 ?, c = 25.7450 ?, V = 2118 ?3) and assessed their thermal stability. The results demonstrate that the La _x Gd_{14-em class="EmphasisTypeItalic ">x} Ge₂B₆O₃₄ (x = 3 and 4) germanate borates codoped with Yb3+–Tm3+ and Yb3+–Er3+ active ions melt congruently at T = 1660 and 1700 K and crystallize with undercooling at T = 1620 and 1660 K, respectively. We have obtained an upconversion luminescence spectrum of the La_3.16Gd₁₀Yb_0.7Er_0.14Ge₂B₆O₃₄ germanate borate. The spectrum shows two bands. The stronger band (in the green region) corresponds to two transitions: 2 H _11/2 ?4 I _15/2 (λ = 525 nm) and 4 S _3/2?4 I _15/2 (λ = 550 nm). The weaker band (in the red region) corresponds to the Er3+ 4 F _9/2?4 I _15/2 transition. Original Russian Text ? V.A. Krut’ko, M.G. Komova, S.A. Novikova, D.V.
