    • PURPOSE: A transition metal stabilized α type sialon phosphor is provided to ensure short reaction time and to solve problems on use of plural gases and a high temperature and high pressure heat treatment. CONSTITUTION: A transition metal stabilized α type sialon phosphor comprises the steps of: (a) performing selfpropagating high-temperature synthesis by injecting a mixture of transition metal oxide, rare earth metal compounds, silicon circle, aluminum source, reducing agent and reaction activator into a high-pressure reactor, and then momentary and locally igniting the mixture in a nitrogen atmosphere; and (b) washing the products with distilled water and then acidic solution.
    • 目的:提供过渡金属稳定的α型赛隆荧光体,以确保反应时间短,解决使用多种气体和高温高压热处理的问题。 构成:过渡金属稳定的α型赛隆荧光体包括以下步骤:(a)通过将过渡金属氧化物,稀土金属化合物,硅环,铝源,还原剂和反应活化剂的混合物注入到自发性高温合成中 高压反应器,然后在氮气气氛中瞬间和局部点燃混合物; 和(b)用蒸馏水然后酸性溶液洗涤产物。
