Although the luminescent properties of carbon dots (CDs) already have been modulated by changing different synthetic parameters, the effect of the reaction time and temperature is still rarely explored. In this work, a facile and eco-friendly synthes

Novel mixed-metal coordination polymers (CPs) based on Pb1−xEux–BDC (x = 0.05, 0.10, 0.25, 0.50 and BDC = 1,4-benzenedicarboxylic acid) are reported. The materials display different coordination structures as the Pb : Eu metal ratio is modified.

Nanocomposites of CdS were prepared in refluxing DMF using a montmorillonite organofunctionalized with thiourea derivatives, with different proportions of the matrix relative to Cd2+ ions. The matrix provided sulfur atoms for CdS formation as well as

Here we report the use of a thiol-functionalized silica-gel to prepare supported CdS nanocrystals by a facile one-step procedure. Upon changing the relative proportion of the matrix we obtained nanocrystals with different average sizes and size distr
