本文试验了合成BaMg_2Al_(16)O_(27):Eu~(2+)的一些主要因素如灼烧温度,一些化学组分改变的影响。试验表明,提高灼烧温度有利于产物发光,但灼烧温度高于1340℃发光亮度不再增加,合适的Eu~(2+)掺入浓度在0·12～0·18克原子范围。Mg~(2+)量和配方中F量的不同对发光亮度、萤光光谱、色纯度和粒度均有影响,通过试验得到了较适宜的BaMg_2Al_(16)O_(27):Eu~(2+)磷光体的制备条件。
In this paper, some main factors of BaMg_2Al_ (16) O_ (27): Eu ~ (2+) were investigated, such as the influence of burning temperature and some chemical components. The results show that increasing the burning temperature is beneficial to the luminescence of the product, but the luminescence brightness no longer increases when the burning temperature is higher than 1340 ℃, and the suitable Eu 2+ concentration is in the range of 0.12-0.18 g atom. The difference of Mg 2+ content and the amount of F in the formulation affected the luminescence intensity, fluorescence spectrum, color purity and particle size. The suitable BaMg 2 Al 16 O 27: Eu 2 +) Phosphor preparation conditions.
