Halide perovskite light-emitting electrochemical cells are a novel type of the perovskite optoelectronic devices that differs from the perovskite light-emitting diodes by a simple monolayered architecture. Here, we develop a perovskite electrochemical cell both for light emission and detection, where the active layer consists of a composite material made of halide perovskite microcrystals, polymer support matrix, and added mobile ions. The perovskite electrochemical cell of CsPbBr₃:PEO:LiTFSI composition, emitting light at the wavelength of 523 nm, yields the luminance more than 7000 cd/m² and electroluminescence efficiency of 1.3×10⁵ lm/W. The device fabricated on a silicon substrate with transparent single-walled carbon nanotube film as a top contact exhibits 40% lower Joule heating compared to the perovskite optoelectronic devices fabricated on conventional ITO/glass substrates. Moreover, the device operates as a photodetector with a sensitivity up to 0.75 A/W, specific detectivity of 8.56×10¹¹ Jones, and linear dynamic range of 48 dB. The technological potential of such a device is proven by demonstration of 24-pixel indicator display as well as by successful device miniaturization by creation of electroluminescent images with the smallest features less than 50 μm.

利用重复频率为1 kHz的钛蓝宝石飞秒激光烧蚀悬浮在甲醇中的单壁碳纳米管制备碳炔。利用表面增强拉曼光谱仪和紫外可见吸收光谱仪对样品溶液进行光谱表征，并用高效液相色谱仪对样品进行分离，确认有碳炔（C_nH₂，n＝6，8，10，12，14，16）生成，其中的主要产物是C₈H₂。对制备碳炔的最佳激光功率与最佳加工时间进行了研究，结果显示：当激光单脉冲能量为0.52 mJ、加工时间为1.5 h时，可以获得最高的碳炔产率。对碳炔的合成机制进行了较深入的解释。激光功率密度存在饱和阈值，该饱和阈值与C₂自由基的碎裂程度有关，激光功率密度超过饱和阈值后会打破C₂自由的“反向” 第四键，进而影响C₂自由基合成碳炔。因此，随着激光单脉冲能量增大，碳炔的产率呈现先增加后降低的现象。本研究可为碳炔的大规模制备提供重要参考。

半导体型单壁碳纳米管在分散与分离过程中长度会被截短。在100nm以下的超短管的存在会增加管间搭接电阻和载流子的散射几率, 从而导致器件性能的下降。开发了一种有机体系的硅胶吸附技术。利用硅胶颗粒表面的硅羟基与包裹在碳纳米管表面的聚合物PCz中的N原子形成氢键, 成功实现了超短碳管的高效去除, 使半导体型碳纳米管的长度分布实现了有效调控。基于长度分选后的碳纳米管制备的晶体管器件, 其开态电流和最大跨导达到8.9μA/μm和0.5mS/μm, 比长度未分选的器件分别提高了约300%和250%。

基于碳纳米材料/体半导体范德华（vdW）异质结的光电器件可以同时实现碳纳米材料的超高载流子迁移率以及体半导体的优异光电性能，且具有结构简单、工艺简便、易于调控界面等优点。尤其是通过调控单壁碳纳米管（SWCNT）的直径/手性、费米能级等可以与体半导体形成能带匹配、具有原子级界面的新型混合维度vdW异质结。本文报道了一种基于（6，5）手性为主的SWCNT薄膜与n型GaAs所形成的pn结的宽光谱自驱动光电探测器，并利用石墨烯降低SWCNT薄膜内载流子的复合几率和促进载流子传输。实验结果表明，器件对405~1064 nm波段光子表现出高灵敏的光电响应，零偏压条件下最大光电响应度和比探测率分别可达1.214 A/W和2×10¹² Jones。

We report on a power-scalable sub-100-fs laser in the 2-μm spectral range using a Tm³⁺-doped ‘mixed’ (Lu,Sc)₂O₃ sesquioxide ceramic as an active medium. Pulses as short as 58 fs at 2076 nm with an average output power of 114 mW at a pulse repetition rate of approximately 82.9 MHz are generated by employing single-walled carbon nanotubes as a saturable absorber. A higher average power of 350 mW at 2075 nm is obtained at the expense of the pulse duration (65 fs). A maximum average power of 486 mW is achieved for a pulse duration of 98 fs and an optical conversion efficiency of 22.3%, representing the highest value ever reported from sub-100-fs mode-locked Tm lasers.

传统光声成像外源对比剂的光吸收主要集中在可见光区和传统近红外区(NIR, 750~900 nm), 开发具有更高光学组织穿透能力的近红外二区(NIR-II, 1 000~1 700 nm)光吸收外源对比剂对活体深层组织光声成像具有重要意义。本文中, 作者选取了光吸收峰在1 000 nm左右的半导体型单壁碳纳米管为近红外二区光学吸收外源对比剂, 测试了其在近红外二区激光激发下能够产生较强的光声效应。进一步地, 作者通过将该纳米材料包埋在仿体组织的不同深度的位置, 获得了仿体组织的深层光声成像, 成像深度可达1.5 cm。试验结果表明, 具有近红外二区光吸收能力的半导体型单壁碳纳米管在活体深层组织光声成像中有很大的应用潜力。

The ideal treatment modality for metastatic cancer would be a local treatment that can destroy primary tumors while inducing an effective systemic anti-tumor response. To this end, we developed laser immunotherapy, combining photothermal laser application with an immunoadjuvant for the treatment of metastatic cancer. Additionally, to enhance the selective photothermal effect, we integrated light-absorbing nanomaterials into this innovative treatment. Specifically, we developed an immunologically modified carbon nanotube combining single-walled carbon nanotubes (SWNTs) with the immunoadjuvant glycated chitosan (GC). To determine the effectiveness of laser irradiation, a series of experiments were performed using two different irradiation durations — 5 and 10 min. Rats were inoculated with DMBA-4 cancer cells, a metastatic cancer cell line. The treatment group of rats receiving laser irradiation for 10 min had a 50% longterm survival rate without residual primary or metastatic tumors. The treatment group of rats receiving laser irradiation for 5 min had no long-term survivors; all rats died with multiple metastases at several distant sites. Therefore, LasertSWNT–GC treatment with 10 min of laser irradiation proved to be effective at reducing tumor size and inducing long-term anti-tumor immunity.
