Despite the outstanding optoelectronic properties of MoS₂ and its analogues, synthesis of such materials with desired features including fewer layers, arbitrary hollow structures, and particularly specifically customized morphologies, via inorganic reactions has always been challenging. Herein, using predesigned lanthanide‐doped upconversion luminescent materials (e.g., NaYF₄:Ln) as templates, arbitrary MoS₂ hollow structures with precisely defined morphologies, widely variable dimensions, and very small shell thickness (≈2.5 nm) are readily constructed. Most importantly, integration of the near‐infrared‐responsive template significantly improves the photoresponse of up to 600 fold in device made of NaYF₄:Yb/Er@MoS₂ compared with that of MoS₂ nanosheets under 980 nm laser illumination. Multichannel optoelectronic device is further fabricated by simply changing luminescent ions in the template, e.g., NaYF₄:Er@MoS₂, operating at 1532 nm light excitation with a 276‐fold photoresponse enhancement. The simple chemistry, easy operation, high reliability, variable morphologies, and wide universality represent the most important advantages of this novel strategy that has not been accessed before.

具有改进的光响应的空心MoS2体系结构的模板化构造

尽管MoS ₂及其类似物具有出色的光电性能，但是通过无机反应合成具有所需特征（包括更少的层，任意的空心结构，尤其是专门定制的形态）的此类材料一直是一项挑战。在此，使用预先设计的掺杂镧系元素的上转换发光材料（例如，NaYF ₄：Ln）作为模板，可以容易地构造出具有精确定义的形貌，宽泛的尺寸和非常小的壳厚度（≈2.5nm）的任意MoS ₂空心结构。最重要的是，在由NaYF ₄：Yb / Er @ MoS ₂制成的设备中，近红外响应模板的集成显着改善了高达600倍的光响应。与在980 nm激光照射下的MoS ₂纳米片相比。通过简单地改变模板中的发光离子（例如NaYF ₄：Er @ MoS _2），可以在1532 nm光激发下以276倍的光响应增强操作来进一步制造多通道光电器件。简单的化学方法，易于操作，高度的可靠性，可变的形态和广泛的通用性代表了这种前所未有的新颖策略的最重要优势。
