2. Phase Modulation Two-Photon Microscopy of Hybrid Halide Perovskite
Abstract : Recently, intense research activities have been focused on solution-processed hybrid lead halide perovskite semiconductors which are being developed for the solar-cell, light emitting diode (LED), and lasing applications. To optimize and fabricate a competitive perovskite-based optoelectronic device, the fundamental studies of the electronic structure, photo-generated carrier dynamics as well as the photoluminescence (PL) & photocurrent (PC) response are necessary and of great significance.

3. Two-Photon Absorption and Photorefraction in Semiconductors and Ferroelectrics
Abstract : Two-photon absorption spectra of Al0.4Ga0.6As/GaAs quantum wells in static electric fields are investigated experimentally. A drastic field-induced increase in the absorption peaks at energies close to half the bandgap energy is reported for the first time. READ MORE

4. A new approach to the analyses of fluorescence depolarisation experiments in the presence of electronic energy transport
Abstract : A new and general procedure is described for a detailed analysis of time-resolved fluorescence depolarisation data in the presence of electronic energy migration. An isotropic ensemble of bifluorophoric molecules (D1-R-D2) has been studied to demonstrate its utility. READ MORE

5. Electronic Energy Migration/Transfer as a Tool to Explore Biomacromolecular Structures
Abstract : Fluorescence-based techniques are widely used in bioscience, offering a high sensitivity and versatility. In this work, fluorescence electronic energy migration/ transfer is applied to measure intramolecular distances in two types of systems and under various conditions. READ MORE
