半導体単一微粒子の光物性と微粒子素子を目指して Optical Properties of Single Nano Particles of Semiconductors and Their Potentialities for Application to Devices
Optical properties of semiconductor nano particles are reviewed, especially on I-VII and II-VI compounds from the view points of fundamental photophysics brought about by quantum size effects on three-dimensionally confined excitonic systems and also of new prospective functional photonic materials. Various kinds of size-dependent excitonic properties in nano particles of individual sizes or individual nano particles are found by means of size-selective excitation and microspectroscopic photo-luminescence measurements. Near-field optical responses in assembled nano particles are also discussed. Their potentialities for application to nano opto-electronic devices are briefly mentioned.
