In article number 1701432, Haiguang Zhao, Zhiming M. Wang, Federico Rosei, and co‐workers report near‐infrared (NIR), heavy metal‐free, colloidal “Giant” CuInSe₂/CuInS₂ core/shell quantum dots (g‐QDs) with tunable absorption and photoluminescence (PL) spectra in the NIR region. These g‐QDs exhibit possess quasi type‐II band energy structure, which is favorable for energy applications. Using this type of QDs to fabricate the photoanode in a photoelectrochemical (PEC) cell demonstrates an efficient and stable PEC device for hydrogen generation. These results indicate that NIR, heavy metal‐free g‐QDs are promising, cost‐effective materials for environmentally friendly optoelectronic devices.

量子点：近红外，不含重金属的胶体“巨”核/壳量子点（Adv。Energy Mater。2/2018）

在文章编号1701432中，赵海光，王志明M.，费德里科·罗西（Federico Rosei）及其同事报告了近红外（NIR），不含重金属的胶体“巨型” CuInSe ₂ / CuInS ₂核/壳量子点（g- QDs）在NIR区域具有可调的吸收和光致发光（PL）光谱。这些g-QD具有准II型能带结构，非常适合能源应用。使用这种类型的量子点来制造光电化学（PEC）电池中的光阳极，证明了一种高效且稳定的氢生成PEC装置。这些结果表明，NIR，不含重金属的g-QD是用于环保型光电器件的有前途且具有成本效益的材料。
