In this thesis we demonstrated a transfer dynamics between InGaN/GaN quantum wells (QWs) and nanomaterials by observing a reduction in the photoluminescence (PL) and time-resolved PL (TRPL) measurements. we introduced InGaN/GaN QWs as donors and PAMAM dendrimers as acceptors. We used TRPL measurements to observe the lifetime changing under room temperature through optical waveguiding, the energy transfer efficiency depended on the distance (d) between the InGaN/GaN QWs and PAMAM dendrimers by a factor of d-2, suggesting a layer-to-layer dipole interactions. The maximum energy transfer efficiency of PAMAM dendrimers system is 72±5%, which has a great potential application in biomedical sensors.
