金属卤化物钙钛矿材料具有极高的射线衰减系数和优良的光电性能,基于其制备的光电探测器和闪烁体已成功用于X射线和γ-射线探测.然而,充分吸收高能射线需要相对较厚的光吸收层,但所需的厚度对于溶液法制备的钙钛矿薄膜来说很难达到.在这项工作中,我们设计了一种复合型器件,其不需要厚的钙钛矿吸收层,而是利用高荧光效率的钙钛矿闪烁体和性能优良的钙钛矿薄膜光电探测器充分吸收和利用X射线,从而提高X射线探测性能.而考虑到钙钛矿闪烁体严重的自吸收,我们将CsPbBr3与含Cu(Ⅰ)的热激活延迟荧光配合物(MAC^(*))Cu(Cz)混合,有效地实现了下转换发光,最大限度地提高了辐射发光量子效率.与商业闪烁体相比,混合闪烁体还实现了更短的余辉.此外,我们系统地研究对比了CsPbIBr_(2)探测器以及复合型探测器的性能指标,发现复合型探测器对X射线的探测灵敏度有显著提高,并且能够实现在X射线下清晰的成像.这项工作为提高X射线探测性能提供了一种新的思路,在应用层面具有巨大的潜力.

为研究毛竹林扩张对植物多样性的影响,在浙江天目山国家级自然保护区内,采用样方调查法对毛竹林、常绿阔叶林、毛竹-常绿阔叶林、针叶林、毛竹-针叶林、针阔混交林、毛竹-针阔混交林等7种群落进行调查,分析毛竹扩张对自然保护区植物群落立木数、不同类型不同层次的物种丰富度、多样性指数及均匀度指数的影响。结果表明:毛竹林的立竹度为3700株·hm-2,毛竹扩散到其他森林类型,均造成其他树种立木数的降低。受毛竹扩张的影响,常绿阔叶林、针叶林、针阔混交林植物群落的乔木层物种丰富度、多样性指数及均匀度有减小的趋势。灌木层中,由于受毛竹扩张的影响,常绿阔叶林和针叶林的物种丰富度、多样性指数及均匀度增大。草本层中,常绿阔叶林和针叶林的物种丰富度、多样性指数及均匀度基本未受毛竹扩张的影响。
