Uniform, well-defined cadmium sulfide@cadmium selenide core/shell quantum dots (CdS@CdSe QDs) were, for the first time, successfully synthesized by a solvothermal method and chemical bath growth for photoelectrochemical activities. The as-synthesized CdS@CdSe QDs not only exhibit superior self-powered photoresponse behavior and excellent stability under ambient conditions but also display significantly improved current densities and photoresponsivity compared to those of individual CdS QDs or CdSe QDs, mainly due to the built-in electric field, and thus have great potential in the fields of renewable energy and renewable energy consumption for carbon neutrality target achievement.
首次通过溶剂热法和化学浴生长成功合成了均匀、定义明确的硫化镉@硒化镉核壳量子点（CdS@CdSe QDs）用于光电化学活性。所合成的CdS@CdSe QDs不仅在环境条件下表现出优异的自供电光响应行为和出色的稳定性，而且与单独的CdS QDs或CdSe QDs相比，其电流密度和光响应性也有显著提高，这主要归因于内置电场，因此在可再生能源和实现碳中和目标的可再生能源消费领域具有巨大潜力。
