1. Introduction
The unprecedented research boom that has occurred over the past two decades with respect to the chemistry of semiconductor nanocrystal quantum dots (QDs) stems from their intriguing electronic and optical properties such as their high surface-to-volume-ratio, size-tunable photoluminescence (PL) spectra, narrow emission and broad absorption spectra, bright fluorescence and high resistance to photo-initiated degradation [1], [2], [3], [4] and [5]. Due to these unique optical properties, QDs have been exploited significantly in processes that require downshifting of light, especially in scientific and technological applications that rely on achieving unique spectral purity at optimum optical flux. Examples of such applications include: optoelectronic devices [6], molecular biology [7], chemical/biological sensing [8] and [9], bioimaging [10], photochemistry [11], etc.
