A Korean researcher announced that he had developed gold nano-particles for use of light-emitting materials, solar cell, biosensor and light emitting efficiency of the phosphor used is about 4 times increased. 

When the light and gold nano-particles meet the surface plasmon resonance is produced, and researchers used that phenomenon in the studies. According to Kim, Dongha(photos), professor of Nano Science at Ewha Womens University, department of chemistry and a team, published the result on the journal, "Scientific Report" in the last month, dated 22nd.

Professor Kim said, "This research is expected to be helpful in the areas of display, biosensor, solar cell, so on."

The heart of Seoul on a shiny day in May

Beautiful Pictures of Seoul 

Can you imagine that the pictures below are from the heart of Seoul ? 

Seoul is a metropolitan city of 10 mil. people. 

However, Seoul is a pretty city surrounded by mountains. And it also has a few at the center.
