Non-thermal pulsed plasma activated water: environmentally friendly way for efficient surface modification of semiconductor nanoparticles

Popis výsledku v původním jazyce

We present an environmentally friendly method of their surface modification. Water treated by discharge is known to produce the so-called plasma activated water, containing a complex mixture of water- and air-originating reactive species. We show that after the treatment of silicon nanoparticles with our plasma activated water, their photoluminescence quantum yield increases several times and their dispersibility in water is significantly improved. We demonstrate that the modification is caused by surface incorporation of nitrate-water complexes, which subsequently leads to a change of surface-oxide-related strain affecting the charge carrier radiative rates. The general applicability of the method is confirmed using commercial MgO and ZnO nanoparticles. Thus, the proposed method enables chemicals-free surface modification of nanoparticles and opens the door for a wide range of variations based on different liquids and discharge parameters.
