| Abstract: | A hightly efficient ultrasonic-assisted method was successfully applied to prepare the strong fluorescence Tb/acetyl acetone(acac) Polyacrylamide(PAM) composite nanoparticles.The nanoparticles are steady fluorescence and highly resistant to photobleaching.A novel fluorescence resonance energy-transfer(FRET) system with Tb/acac/PAM as donor and Rhodamine B as acceptor was set up efficiently. |
