• Analysis of fluorescence generation mechanisms, including cluster-triggered emission (CTE).
• Categorization of preparation methods (physical, chemical, in situ synthesis, hybrid) and morphological dimensions.

Main Results:

• Polysaccharides can intrinsically generate fluorescence or act as carriers/enhancers for fluorescent components.
• Various preparation techniques yield polysaccharide-based FMs with tunable properties.
• Significant application potential exists in environmental monitoring, biomedicine, anti-counterfeiting, and smart textiles.

Conclusions:

• Polysaccharides are pivotal for advancing green fluorescent materials.
• Further research is needed to address current challenges and explore future trends in polysaccharide-based FMs.
• This review provides a theoretical basis and practical guidance for sustainable FM development.
