研究人员在新型多功能纳米材料的研发上付出了诸多努力,并将其广泛应用于生物医学领域。其中,长余辉发光材料和上转换发光材料在生物成像、生物传感和癌症治疗等领域的发展,具有潜在应用前景。但是,长余辉发光材料和上转换发光材料的开发仍然面临着一些挑战。部分长余辉发光材料中能量的耗尽可以被光激励持续发光策略恢复,但大部分长余辉发光材料充电效率差,发射强度和穿透深度仍然受到限制,满足不了在体内重复激发以便用于长期成像应用的需求;上转换发光材料内部的非辐射能量损失和其他损耗机制的存在,导致发光效率较低,并且发光时间有限。基于以上问题,可以通过发射波长在近红外第二（NIR-II）生物窗口的长余辉发光材料来解决长余辉发光穿透深度受到限制的问题;通过将长余辉发光材料和上转换发光材料的结合来解决长期成像应用的需求。在第一项工作中,我们采用水热合成法,制备了发射波长位于NIR-II生物窗口的Ni2+掺杂镓酸锌Zn1+2xGa2-2xO4:Nix2+（ZGO:Ni）长余辉发光材料,ZGO:Ni在1000～1500nm之间出现宽带发射峰。系统地研究了不同煅烧温度和p H值以及Ni2+不同掺杂比例对ZGO:Ni发光特性的影响。采用XRD、TEM、EDS、荧光光谱仪进行测试,对制备的ZGO:Ni进行了表征,并研究了其光致发光性能、余辉发光性能和发光机理。结果显示,通过优化煅烧温度和p H值以及Ni2+的掺杂量,确定了当ZGO:Ni的煅烧温度为1000℃、p H值为8、Ni2+的掺杂量1%时发光性能最佳,发射波长位于1290 nm处。在第二项工作中,我们构建了Zn Ga2O4:Ni2+/Na Er F4:Yb3+,Mn2+（ZGO:Ni/UCNPs）上转换长余辉纳米复合材料。我们采用水热合成法,制备了激发源为980 nm激光、发射波长在600-700 nm范围内的Na Er F4:Yb3+,Mn2+上转换发光材料,基于荧光共振能量转移体系,通过共价键将Zn Ga2O4:Ni2+与Na Er F4:Yb3+,Mn2+结合。所得到的复合材料用980 nm激光激活后,在1290 nm处呈现持续发光。这是由于980 nm激光激发后,Na Er F4:Yb3+,Mn2+的发射光谱与Zn Ga2O4:Ni2+的激发光谱有良好的重叠,使得Na Er F4:Yb3+,Mn2+中的Er3+和Zn Ga2O4:Ni2+中的Ni2+之间发生荧光共振能量转移。ZGO:Ni/UCNPs上转换长余辉纳米复合材料的构建,解决了光激励持续发光策略不能满足体内重复激发以供长期成像应用需求的问题。此外,因为复合材料的激发（980nm）和发射（1290 nm）波长位于生物NIR-I、NIR-II生物窗口内,适合用于深层组织的生物成像,因此,该复合材料在体内生物成像方面有巨大的应用潜力。

为探讨利用三波段植被指数(three-band index,3BI)对春小麦叶片水分含量(leaf water content,LWC)估算的可行性,在田间尺度上,利用ASD-FieldSpec-3光谱仪测定春小麦抽穗期冠层光谱反射率,采用任意波段组合方法,分别建立两波段植被指数(two-band index,2BI)包括比值植被指数(RVI)、归一化植被指数(NDVI)、差值植被指数(DVI)及3BI,并对单波段反射率、两波段植被指数和三波段植被指数与春小麦抽穗期LWC之间进行相关性分析,筛选稳定的光谱参数,基于人工神经网络(artificial neural network,ANN)、K近邻(K-nearest neighbors,KNN)和支持向量回归(support vector regression,SVR)等3种机器学习算法,建立有效波段组合运算的抽穗期春小麦LWC估算模型,并利用独立样本对模型精度进行检验和评价。结果表明,单波段反射率、2BI和3BI与春小麦抽穗期LWC之间的相关性均达极显著水平(P<0.01),而相关系数差异较大,绝对值分别为0.23、0.62、0.94,说明组合波段展现了光谱隐含信息,避免有效光谱信息的丢失;估算模型中,春小麦抽穗期以KNN算法和最佳3BI组合变量(3BI-5(1075,1095,1085)、3BI-6(1100,400,1097))构建的模型拟合度最高(r^(2)=0.83),均方根误差最小(RMSE=2.14%),相对偏差百分比超出了2.0以上(RPD=2.31),说明该模型具有一定的预测能力。由此可见,通过任意波段组合,可明显提高3BI与春小麦LWC的关联度,且基于K近邻算法构建的模型具有较好的稳定性和估算能力。
