Abstract
Chapter 2. Silicon Quantum Dots (SiQDs) derivatized with organic fluorophore such as siloles were successfully synthesized from the reaction of ammonium chloride, magnesium silicide, and 1-chloro-1-methyl-2,3,4,5-tetraphenyl-silole in DMF. Optical characterizations of SiQDs were achieved by using ultraviolet-visible (UV-Vis) and photoluminescence (PL) spectroscopy. Silole-derivatized SiQDs were characterized by nuclear magnetic resonance (NMR). SiQDs synthesized without silole were emitted the light at 460 nm with an excitation wavelength of 400 nm. The emission wavelength of 1-chloro-1-methyl-2,3,4,5-tetraphenyl-silole is 500 nm with an excitation wavelength of 360 nm. After the synthesis of Si QD/silole nanoparticles, Si QD/silole nanoparticles were subjected to measure the PL. Detailed information about the photoluminescence will be discussed.
