Latent fingerprint detection
Non-conjugated
The stöber method
- 摘要：In this paper, non-conjugated organosilicone fluorescent nanoparticles (Si-NPs) were synthesized by the Stöber
method. The Si-NPs have a diameter of approximately 30 nm, uniform particle size, and a quantum yield of up to
70.6% ultra-bright blue light emission. The prepared non-conjugated siloxane fluorescent small molecule is
covalently bonded to the silica matrix. The Si-NPs exhibited excellent stability in ultraviolet irradiation and a
wide pH range, and their improved stable optical properties are attributable to the protection of the silica matrix.
In addition, the effectiveness of Si-NPs for potential fingerprint detection on a variety of substrates is demonstrated. Clear optical/fluorescent images of the ridges and spaces with high contrast and resolution are obtained
because the particle size of the obtained Si-NPs is much smaller than the width of the fingerprint ridges.
