Abstract Fluorescent dye-diatomite composites were prepared based on adsorption process. Fluorescence properties of the composites were characterized by fluorescence spectrophotometer. According to the fluorescence spectra of the composites, latent fingerprints on various substrates were developed via selecting appropriate excitation lights and optical filters. Finally, integrating forensic science frontiers into chemical experiment teaching by utilizing the mechanism of fluorescence phenomena in fingerprint development would improve students' experiment skill, develop their scientific thinking and improve their innovation consciousness.
