What type of compounds may be utilized as fingerprint powders in latent print analysis?

The use of phosphors as fingerprint powders in latent print analysis is well-founded due to their ability to fluoresce under specific light wavelengths. This fluorescence enhances visibility and contrast when examining latent prints, especially on surfaces where traditional powders may not be as effective. The phosphorescent properties can help in detecting prints that might be otherwise overlooked, particularly in challenging forensic environments.

While carbons, oxides, and solvents can play a role in different aspects of fingerprint analysis, they do not possess the same level of efficacy in enhancing latent prints as phosphors. For example, carbon powders can sometimes be used but may not provide the same visibility advantages that phosphor powders do under ultraviolet or other specific lighting conditions. Oxides and solvents, on the other hand, are generally not used as powders for this purpose, as they do not offer the required contrast or stability in the way that phosphors do. Thus, phosphors stand out as the most suitable choice for enhancing latent fingerprints in practical forensic applications.
