Abstract

Herein, copper cysteamine (CC) was loaded with montmorillonite (MMT) to form a montmorillonite-copper cysteamine (MCC) composite that showed enhanced fluorescence properties. This enhancement was determined to have arisen from electron transfer, improved structural stability, and a nonradiative deactivation process.
