A Photochemical Avenue to Photoluminescent N-Dots and their Upconversion Cell Imaging

Scientific Reports, 2017
A photochemical avenue to synthesize nitrogen-rich quantum dots (N-dots) using 2-azido imidazole as the starting material was established for the first time. A production yield of up to 92.7% was obtained.

Plasmon-enhanced upconversion photoluminescence: Mechanism and application

Reviews in Physics, 2019
Abstract The enhanced local electromagnetic field (EM) excited on the noble metallic nanostructure exhibits potential application in various areas, particularly in surface-enhanced spectroscopy (SES). Resonant coupling of SPs to luminous centers can strongly moderate the emission spectra properties, including the angular distribution, the intensity ...
