Micro-structured fluorescent powders for detecting latent ...
Jan 01, 2019·Fig. 3, Fig. 4 show images of fingerprints before and after processing with silica-based fluorescent micro-structured powders (SC4-E30) on non-porous and porous surfaces, respectively. The SC4-E30 powder was chosen to perform most of the studies due to its higher fluorescence intensity in relation to the others developed powders.
