在这项工作中，我们报告的修改市售的电化学电极与氧化锡（SnO 2）和Pd掺杂的SnO 2（Pd-SnO 2）通过脉冲激光诱导正向转移（LIFT）。作为原位脉冲光热处理工作的脉冲光照射允许SnO 2和Pd-SnO 2从UV吸收金属络合物前体转移到柔性的市售丝网印刷电极上。优化了激光转移条件，并对不同条件下转移的材料进行了形态学和化学评价，并对其功能性进行了铜离子检测。例如，通过施加100-250 mJ/cm 2范围内的激光能量密度，转移特征的形状和尺寸范围从纳米多面体到近角生长的立方体Pd-SnO 2或近立方体Pd-SnO 2。此外，EDX分析与XPS结果一致，即，在激光转移之后，在Pd-SnO 2像素中存在低于0.5%的Pd量。进行了第一次传感测试和转移的Pd-SnO 2证明，以增强阴极峰时，暴露于Cu（II）离子。这种光引发的制造技术为低成本和高通量制造金属氧化物以及用于重金属离子检测的电极开辟了一条有前途的道路。
In this work, we report the modification of commercially available electrochemical electrodes with tin oxide (SnO2) and Pd doped SnO2 (Pd-SnO2) via pulsed laser-induced forward transfer (LIFT). The pulsed light irradiation working as in situ pulsed photo-thermal treatment allows for the transfer of SnO2 and Pd-SnO2 from UV absorbing metal complex precursors onto flexible, commercially available screen-printed electrodes. The laser transfer conditions are optimized and the material transferred under different conditions is evaluated morphologically and chemically, and its functionality is tested against the detection of copper ions. For example, by applying laser fluences in the range 100–250 mJ/cm2, the shape and the size of the transferred features ranges from nano-polyhedrons to near corner-grown cubic Pd-SnO2 or near cubic Pd-SnO2. In addition, the EDX analysis is consistent with the XPS findings, i.e., following laser transfer, Pd amounts lower than 0.5% are present in the Pd-SnO2 pixels. First sensing tests were carried out and the transferred Pd-SnO2 proved to enhance the cathodic peak when exposed to Cu(II) ions. This photo-initiated fabrication technology opens a promising way for the low-cost and high-throughput manufacturing of metal oxides as well as for electrodes for heavy metal ion detection.
