Abstract :
Summary form only given. We use femtosecond three photon echo (SPPE) experiments nanosecond transient hole-burning (HB) spectroscopy to investigate the electronic structure and dephasing dynamics in this novel material. The 29-/spl Aring/ diameter InP nanocrystals used in this study are embedded in a 200-/spl mu/m free-standing polymer (PVB) film.
