【摘要】 用KH570+AA/MMA对铝酸锶进行试验以改善其耐水性。检测结果表明,产品被完整紧密包覆,表现出优良的耐水性能。在纯水中,原样2h内即完全水解,而产品在100h内无水解。同时,包覆对颜料的发光性能影响很小,发射光和激发光强度损失在6%以下。更多还原

【Abstract】 The organic encapsulation on SrAl₂O₄:Eu²⁺,Dy³⁺ phosphors was firstly studied by using silicane coupling agent-KH570 to introduce polymerizable groups onto phosphors′ surface.The measurement results of FL、SEM and TEM showed that the encapsulation film was composed of polyallylmethacrylate modified by silicane.The measurement results of water-resistance and luminescent properties indicated that the encapsulated SrAl₂O₄:Eu²⁺,Dy³⁺ phosphors had better water-resistance performance,and still kept good persistent photoluminescent properties.更多还原
