市场上大量出现的新型强磷光材料——人造硼铝酸锶,被广泛应用于雕刻艺术品,制造各种首饰和夜明珠等产品。本文通过系统测试研究得知,该种材料的主要矿物组成为微晶铝酸锶和玻璃相的氧化硼,只有合成时在特定的煅烧温度(1 300℃)和时间控制(3h)下,形成的材料才具有长余辉特征。因在自然界中尚未发现与其对应的晶质或非晶质体,所以命名为人造硼铝酸锶[1]。且其发光特性与所含有的少量稀土元素Eu3+、Dy3+有关。
Emerging on the market a large number of new strong phosphorescent material - artificial strontium aluminoborate, is widely used in carving works of art, making a variety of jewelry and night pearl and other products. In this paper, we know from the systematic testing that the main minerals of this kind of material are strontium aluminate and glassy boron oxide, which are formed only under specific calcination temperature (1300 ℃) and time control (3h) The material has long afterglow characteristics. Because in nature has not yet found its corresponding crystalline or amorphous body, so named strontium aluminoborate [1]. And its light-emitting characteristics and contains a small amount of rare earth elements Eu3 +, Dy3 + related.
