“…These peculiar features give the possibility to tune the luminescence spectrum of NCs in a wide range of wavelengths just by playing with size at the nanoscale. Semiconductor quantum dots can be fabricated via several techniques [2][3][4]. In this work, CdS NCs have been prepared by means of thermal decomposition of precursors in a hot mixture of surfactants with non-coordinating solvent [5].…”

“…20,21 Several techniques for the CdS synthesis have been demonstrated. 22,23 For instance, highly luminescent cadmium selenide/cadmium sulfide (CdSe/CdS) and cadmium selenide/zinc sulfide (CdSe/ZnS) core-shell nanoparticles have been prepared through organometallic approaches. 24 However, organometallic reactions are typically carried out in the organic phase and at high temperatures above 200 C. Recently, Pan et al have reported a two-phase method with mild conditions that results in highly luminescent nanoparticles.…”

Inkjet printing and low temperature sintering of CuO and CdS as functional electronic layers and Schottky diodes

Here we report on inkjet printing of a conductive amorphous copper oxide (CuO) ink and of semiconducting cadmium sulfide (CdS) quantum dots under ambient conditions and at low temperature to form functional thin films, which were used for the fabrication of Schottky diodes. Inkjet printed CuO features were sintered using a commercial photonic sintering tool in order to form the diode rectifying contacts. This was accomplished by using the tool's proprietary high-intensity flash lamp at very short pulse durations, ensuring a low processing temperature that favors the usage of low-cost substrates. The photonic sintering method was also used for sintering CdS films, resulting in a more efficient removal of the organic moieties around the CdS nanoparticles than a wet chemical KOH treatment. The here reported process allows the deployment of a low-cost polyethylene terephthalate (PET) polymer foil as the substrate material. The initial results showed modest performance of th e fabricated Schottky diode. Nevertheless, the general approaches demonstrate new routes for low temperature manufacturing methods for functional electronic layers based on accordingly developed functional materials utilising amorphous metal oxides and quantum dots
