The basic understanding of excited state dynamics of photo excited quantum dots is essential for technological applications such as efficient solar energy conversion, light emitting diodes, photovoltaic cells and so on. Our emphasis is directed to understand the influence of size, shape and composition of quantum dot on their carrier relaxation processes, (i.e. radiative, nonradiative relaxation rate and number of trap states) and resonance energy transfer process. A stochastic model of carrier relaxation dynamics in semiconductor QDs has been proposed to correlate with the experimental results. Fluorescence dynamics and electronic interactions of graphene oxide with CdTe QD in graphene oxide-CdTe QD composite will be highlighted. We will discuss porphyrin based nano/micro assemblies and their efficient photocatalytic behavior. Finally, we highlight the fundamental photophysics of dye doped polymer nanoparticles for photonics and bio-photonics applications.
