Polymethyl methacrylate (PMMA) plate luminescent solar concentrators with a bottom-mounted (BM-LSCs) photovoltaic (PV) cell are fabricated by using a mixture of Lumogen Red 305 and Yellow 083 fluorescent dyes and a commercial monocrystalline silicon cell. The fabricated LSC with dye concentrations of 40 ppm has the highest power gain of 1.50, which is the highest value reported for the dye-doped PMMA plate LSCs. The power gain of the LSC comes from three parts: the waveguide light, the transmitted light, and the reflected light from a white reflector, and their contributions are analyzed quantitatively. The results suggest that the BM-LSCs have great potential for future low-cost PV devices in building integrated PV applications.

由相对论电子束激发稀有气体Kr和碱金属Li的混合蒸气,观察到来自Kr Li准分子离子的真空紫外发射带(147 nm和149 nm)。讨论了发射光谱的温度和气体密度依赖特性以及电子束激发的动力学过程。经理论计算,两个发射带被分别标识为(KrLi) 离子准分子的21Σ →11Σ 和11Π→11Σ 跃迁。另外,在Xe/Li混合蒸气中观察到的186 nm和189 nm辐射带也被标识为准分子离子Xe Li对应能级之间的跃迁。

光诱导光子晶格是一种周期光学系统,其对光束传输的控制在全光交换、光开关等方面具有潜在应用。运用优化的交替隐式差分波传输法对非线性薛定谔方程进行数值仿真,研究了涡旋光束在光诱导自聚焦类方晶格中的传播特性、光子晶格对光束传输的影响以及形成涡旋孤子的条件。研究发现,不存在晶格时,涡旋光束会由于自聚焦效应而分裂成基态孤子;存在晶格时,离散涡旋孤子的稳定传输与外加电场、晶格深度、输入光强有关,非格点激励的一
本文在正六边形光子晶体光纤长周期光栅包层空气孔中选择性填充液体材料,设计并优化一种高灵敏度长周期光栅双谐振温度传感器。基于模式耦合理论建立光纤光栅传感模型,发现在包层空气孔填充特定折射率液体材料后,同一光栅周期下,模型分别在短波长、长波长处出现透射谐振峰,然后利用全矢量有限元法在完美匹配层边界条件下对模型的温度特性进行了数值分析。结果表明:当包层空气孔中填充磁流体时,随着温度的升高,左峰(短波长处)中心波长蓝移,右峰(长波长处)中心波长红移,且左、右峰间隔随温度变化曲线近似线性,其温度灵敏度为11.40
