摘要
长余辉材料作为一种特殊的光致发光节能材料,在显示、生物医学、能源及环境工程等领域有着广泛的应用。以Sr_(2)MgSi_(2)O_(7)为代表的硅酸盐材料具有耐水性强、化学稳定性好、余辉时间长等优点,是一类极具潜力的长余辉材料。但余辉发光强度不足、发射带窄以及余辉机理不明确等缺点限制了其进一步商业化应用。全面回顾了Sr_(2)MgSi_(2)O_(7):Eu^(2+),Dy^(3+)长余辉材料的发展历程,系统综述了Sr_(2)MgSi_(2)O_(7):Eu^(2+),Dy^(3+)长余辉材料的余辉发光机理及其在安全标识、生物成像、光催化领域的应用,并对亟需解决的问题及今后的发展方向进行了探讨。
Long-afterglow phosphor is a unique photoluminescent energy-saving material having widespread applications in the areas of displays, biomedicine, energy, and environmental engineering. Sr_(2)MgSi_(2)O_(7):Eu^(2+),Dy^(3+),as representative silicate material, is one of the most promising long-afterglow phosphors owing to its excellent water resistance, good chemical stability, and long afterglow time. However, its further commerical application is limited by insufficient afterglow intensity, narrow emission bands, and unclear afterglow mechanism. In this review, we give a comprehensive introduction of the history of Sr_(2)MgSi_(2)O_(7):Eu^(2+),Dy^(3+) long-afterglow phosphor. In addition,we summarize the recent advances of Sr_(2)MgSi_(2)O_(7):Eu^(2+),Dy^(3+) in terms of afterglow mechanism and diverse applications, including safety signs, bio-imaging, and photocatalysts. Finally, the urgent problems to be solved and potential future directions of Sr_(2)MgSi_(2)O_(7):Eu^(2+),Dy^(3+) are discussed.
