NIR luminescence for the detection of latent fingerprints based on ESIPT and AIE processes

Abstract

A facile NIR probe NIR-LP based on the ESIPT–AIE processes for the detection of the latent fingerprints (LFPs) was developed for the first time.

Preparation, characterization, and application of a lipophilic coated exfoliated Egyptian blue for near-infrared luminescent latent fingermark detection

“…However, there are many potentially interfering substances that also fluoresce within this region and could contribute to background interference, including printing inks, bodily fluids, and optical brighteners [4][5][6]. Nearinfrared (NIR) region (700-1000 nm) luminescent materials have potential to improve detectability of fingermarks since very few substrates luminesce strongly in this region [6][7][8][9]. Despite this advantage, only a limited number of NIR luminescent powders have been reported [10][11][12][13].…”

Luminescent nanostructures for the detection of latent fingermarks: A review

“…Xu, He, et al, 2014), and polymer dots including conjugated polymer dots (H. Chen et al, 2015;H. Chen, Ma, et al, 2017;X. Jin et al, 2015) and conjugated polyelectrolyte dots (B. I.…”

“…X. Jin et al (2015) introduced 4-dimethylamino-20-hydroxychalcone nanoparticles as a novel aggregation induced emission probe which luminesced at 600-800 nm when illuminated at 365 nm by a UV lamp. These nanoparticles successfully developed fresh and aged charged fingermarks on aluminum foils, coins and glass slides with high sensitivity.…”

Molecular and crystalline requirements for solid state fluorescence exploiting excited state intramolecular proton transfer

“…[28][29][30][31][32][33] Chalcone-based compounds, comprising an aromatic ketone and enone system, have found application in both technological and biological settings. [33][34][35][36][37][38][39][40][41][42][43][44][45][46][47][48] The lasing prop- 1. [49][50][51] All reported quantum yields were obtained for single crystals, consequently the effect of trapping as a source of loss of efficiency can be ruled out.…”
