Cadmium, colloidal

Let us add here that the fabrication of polycrystalline semiconductive films with enhanced photoresponse and increased resistance to electrochemical corrosion has been attempted by introducing semiconductor particles of colloidal dimensions to bulk deposited films, following the well-developed practice of producing composite metal and alloy deposits with improved thermal, mechanical, or anti-corrosion properties. Eor instance, it has been reported that colloidal cadmium sulfide [105] or mercuric sulfide [106] inclusions significanfly improve photoactivity and corrosion resistance of electrodeposited cadmium selenide.

The enhancement can be explained also by an excitation transfer from Si nanocrystallites to Eu ions. Other authors [10] have shown similar results by comparing the PL of Eu in silica gel and in silica gel with colloidal cadmium sulfide. They show that CdS nanoparticles enhanced Eu fluorescence due to energy transfer from a surface trap in the CdS particles to Eu ions. [Pg.118]
