〇Kosuke Inoue¹, Takuya Kojima¹, Hiroshi Sugimoto¹, Minoru Fujii¹ (1.Kobe Univ.)

Keywords:silicon quantum dots, photoluminescence

In the lecture, we show the change of luminescence characteristics when sodium sulfite concentration, irradiation light intensity, irradiation time, irradiation light wavelength, silicon quantum dot size etc. are changed. And we discuss the mechanism of photoinduced charge transfer between silicon quantum dots and sodium sulfite.
