在这里，我们提出了一种简单的策略来提高水敏SrLiAl3N4：Eu2+荧光粉的稳定性，方法是采用玻璃中荧光粉(PIG)的方法将荧光粉颗粒嵌入到低熔点的SnP-F-O玻璃中。在水中浸泡96 h后，SrLiAl3N4：Eu2+-PIG样品的发光强度保持在原始强度的80%，表明SrLiAl3N4：Eu2+的耐湿性显著提高。采用窄带红色发光材料SrLiAl3N4：Eu2+-PIG和蓝光COB(Chip-on-board)制作了植物生长LED器件。该器件的发射光谱与植物对叶绿素(a和b)的吸收光谱吻合较好，表明所制备的SrLiAl3N4：Eu2+-PIG适合应用于植物照明领域。我们相信，这一简单的方法可以很容易地扩展到其他水敏发光材料。
Herein, we present a simple strategy to enhance the stability of water-sensitive SrLiAl3N4:Eu2+phosphor through embedding the phosphor particles into low-melting Sn-P-F-O glass using phosphor-in-glass (PiG) approach. After being immersed in water for 96 h, the emission intensity of the SrLiAl3N4:Eu2+-PiG sample was maintained at 80% of its pristine intensity, indicating the moisture-resistance property of SrLiAl3N4:Eu2+was significantly enhanced. Employing the narrow-band red-emitting SrLiAl3N4:Eu2+-PiG sample and a blue COB (chip-on-board), a plant growing LED device was fabricated. The emission spectrum of the device matches well with the absorption of Chlorophyl (a and b) in plants, indicating the as-prepared SrLiAl3N4:Eu2+-PiG are suitable to be applied in plant lighting field. We believe that this simple method reported in this communication can be easily expanded to other water-sensitive luminescence materials.
