Tuning CdTe quantum dots reactivity for multipoint detection of mercury(II), silver(I) and copper(II)

Autor: Ricardo N.M.J. Páscoa, João L.M. Santos, José X. Soares, S. Sofia M. Rodrigues, Rafael C. Castro, David S.M. Ribeiro

Publikováno v: Journal of Luminescence. 207:386-396

In this work we tuned the surface chemistry of distinctly-sized CdTe quantum dots (QDs), by using a variety of capping ligands with distinctive functional moieties, and combined them in multi-QDs probing solutions for Hg2+, Cu2+ and Ag+. Upon the ind
