Abstract
Based on carbazole derivatives, a new fluorescent dye G-D was constructed. White fluorescent fingerprint powder was constructed by proportionally blending montmorillonite with G-D and the previously synthesized dyes (B-D and R-D). White fluorescent fingerprint powder is obvious in the dark and can be subjected to minimal fluorescent background interference. The white fluorescent fingerprint powder was successfully used to develop latent fingerprints left on various surfaces, including glass, tin foil, marble, acrylic plate with bright fluorescence, painted wood and coins. Impressively, the white fluorescent fingerprint powder also has excellent applications in developing aged fingerprints and replication. For complex criminal investigation activities, the white fingerprint powder with high resolution, wide applicability and real-time development is a competitive visualization means.
