Copper and Nitrogen Codoped CDs for Alleviating the Damage of Reactive Oxygen Species for Cucumber Seedlings under Salt Stress.

Dramatic changes in climate and soil environments have made growing conditions for crops more challenging. These crops are subject to a range of abiotic stresses in different environments, which can lead to significant yield losses, resulting in economic and environmental damages. Herein, we report a straightforward one-pot hydrothermal method for creating carbon dots codoped with copper and nitrogen (Cu,N-CDs).
