초록

Dihydrotetraphenylgermole has been synthesized from the reduction of dichlorotetraphenylgermole with lithiumaluminiumhydride. UV-Vis absorption and photoluminescence was measured by using UV-Vis and fluorescence spectroscopy. Nanoparticles of dihydrotetraphenylsilole were synthesized from the mixture solution of water and THF. Photoluminescence behavior of organogermanium nanoparticle was investigated at various water fractions. Critical fraction of water to form organogermanium nanoparticles was 60%. Photoluminescence intensity of organogermanium nanoparticle was increased as the concentration of organogermanium nanocolloids increased. Photoluminescence efficiency of organogermanium nanoparticle at 90% water fraction increased about 100 times compared to that of molecular state.
