Enhanced photostability of aqueous solution of Rhodamine 6G with gold nanoparticles in lasing process by silica coating

Not Accessible

Your library or personal account may give you access


Gold nanoparticles are mixed in aqueous solution of Rhodamine 6G to modify the lasing output intensity. The photostability deterioration of the gain medium by gold nanoparticles is successfully compensated by silica coating on the nanoparticles.
