Adaptive fluoride ceramic with glass forming layer (GCZBL-Er) used in laser anti-escaping has been prepared by one-step synthesis, and the thickness of glass layer is identified as ~0.41 mm. Blue, green and red emissions of Er3+/Yb3+ codoped fluoride ceramic (CZBL-Er) and glass layer (GZBL-Er) have been investigated under ~980 nm laser pumping. With the forming of thin glass layer on ceramic surface, the absorption intensities on diffuse reflection of GCZBL-Er at 974 nm and 1.53 μm increase by 48% and 53% than those of CZBL-Er. Excited by a 979 nm laser, the presence of the glass layer increases the absolute absorption rate in spectral power from 75% in CZBL-Er to 83% in GCZBL-Er, which is consistent with the improvement in the absorbed photon number. In addition, the quantum yield of GCZBL-Er complex is raised by 28.4% compared to the case of ceramic substrate by photon quantification. Intense absorption-conversion ability and efficient macroscopical anti-escaping effect confirm the superiority of ingenious structure in the fluoride ceramics with glass forming layer, which provides a new approach for developing the absorption-conversion materials of anti-NIR laser detection.

具有玻璃形成层的掺稀土氟化物陶瓷中的入射激光防逃逸。
通过一步合成制备了用于激光防逃逸的带有玻璃形成层的自适应氟化物陶瓷(GCZBL-Er),玻璃层的厚度确定为〜0.41 mm。在〜980 nm激光泵浦下研究了Er3 + / Yb3 +共掺杂氟化物陶瓷(CZBL-Er)和玻璃层(GZBL-Er)的蓝,绿和红色发射。随着陶瓷表面薄玻璃层的形成,GCZBL-Er在974 nm和1.53μm处的漫反射吸收强度比CZBL-Er分别增加48%和53%。在979 nm激光的激发下,玻璃层的存在将光谱功率的绝对吸收率从CZBL-Er中的75%提高到GCZBL-Er中的83%,这与吸收光子数的提高是一致的。此外,GCZBL-Er配合物的量子产率提高了28。通过光子定量,与陶瓷基板的情况相比为4%。强大的吸收转换能力和有效的宏观防逸作用证实了具有玻璃形成层的氟化物陶瓷巧妙结构的优越性,为开发抗近红外激光检测吸收转换材料提供了新的途径。
