摘要: Glass and products of solid-phase synthesis in the form samarium-activated single-phase powders with huntite structure were obtained system Y2O3–Al2O3–B2O3. It was shown that glasses studied crystallize predominately aluminum borate Al4B2O9 precipitating bulk solid solution (Y, Sm)Al3(BO3)4 on surface sample. When crystalline (Sm x Y1 – )Al3(BO3)4 transitioned into an amorphous state leveling Stark broadening luminescence bands Sm3+ observed, but branching ratios changed very little. found lowering temperature such from 1450 to 1250°C increases BO4 fraction quantum yield low activator concentration.
