摘要/Abstract

摘要： 以纳秒脉冲二极管激光作为泵浦源, 研制了一款高灵敏瞬态吸收光谱仪, 该光谱仪利用平衡探测器的原理, 宏脉冲和子脉冲的时序结构, 并结合电子学延时方式, 避免了频繁的平衡操作, 从而实现了高灵敏度瞬态吸收 (∆A<5 × 10^-6 ) 的快速测量。利用该光谱仪测量了甲铵铅碘 (MAPbI3) 钙钛矿薄膜材料在不同泵浦功率密度下的载流子动力学, 发现了泵浦功率密度依赖的动力学现象, 并且实现了在低载流子浓度下线性响应区的载流子动力学测量。进一步测量和比较了MAPbI3钙钛矿薄膜在296 K和220 K下的载流子动力学, 发现低温能延长载流子寿命, 原因是在低温下, 电离化的杂质辅助电荷复合速率减小。本研究提出的高灵敏瞬态吸收方法可以拓展到全纳秒脉冲二极管激光系统, 这不仅会降低瞬态吸收光谱仪的成本, 同时在快速评估材料在太阳光照低载流子浓度下的本征性能方面也有潜在的应用。

Abstract: A highly sensitive transient absorption spectrometer was developed in this work using a nanosecond pulse diode laser as a pump source, and rapid and high sensitivity transient absorption ( ∆ A<5×10−6 ) was achieved by using the balanced detection, the timing structure of macro-pulse and micro-pulse and an electronic delay scheme to avoid repetitive balancing. Then, the carrier dynamics of methylammonium lead iodide (MAPbI3) thin film perovskite materials at different pump power densities were measured using the developed spectrometer, and pump power density-dependent dynamic phenomena were observed. Especially, the measurement of carrier dynamics in the linear response region was achieved at low carrier concentrations. Furthermore, the carrier dynamics of MAPbI3 at 296 K and 220 K were measured and compared, and it was found that the carrier lifetime was extended at low temperature due to the reduction of charge recombination assisted by ionization impurities. The highly sensitive transient absorption method proposed in this work can be extended to full nanosecond pulse diode laser systems, which will not only reduce the cost of transient absorption spectrometers but also have the potential applications in rapidly evaluating the intrinsic properties of materials at low carrier densities under solar illumination.

Key words: nanosecond time-resolution, photoluminescence, transient absorption, carrier dynamics, methylammonium lead iodide
