, anti-counterfeiting inks). They enable the sensitive detection of pollutants, facilitate high-performance bioimaging, and enhance the efficiency of energy devices. However, PTMCs face several challenges, including complex synthesis, limited thermal and photostability, solubility issues, and environmental and toxicity concerns. Additionally, high production costs, instability in different media, and the need for optimized energy transfer efficiency must be addressed to enhance their practical performance. This review explores the mechanisms behind AEE in PTMCs and discusses strategies for overcoming these challenges, including ligand engineering, hybrid material development, and sustainable synthesis methods. It also highlights their potential in advancing energy-efficient technologies, precision therapeutics, and secure communication systems, contributing to a more sustainable and innovative future.
