Abstract

A noticeable repositioning of the characteristic photoluminescence peaks of homogeneous colloidal quantum dot solutions has been observed upon producing heterogeneous combinations of previously synthesized quantum dots. Typically, the wavelength of an emission peak is described as a fermionic property solely dependent on the size and the chemical composition of the nanoparticles involved. However, the experimental observations indicate that quantum dot interactions produce surface energy variations that trigger the aforementioned repositioning of photoluminescence emission peaks, and could represent an alternative route for controlling other fermionic properties such as melting temperature, ferromagnetic properties, cohesive energy, activation energy of diffusion and vacancy formation energy. Therefore, the extensive characterization of quantum dot interactions for tailoring and controlling fermionic properties could enable the demonstration of novel nanomaterials with unique properties for a variety of optoelectronic, photovoltaic and biomedical applications.
