| Abstract: | Size effect of silver nano particles on the photophysical properties of 1,4-dihydroxy-2,3-dimethyl-9,10-anthraquinone (DHDMAQ)
have been investigated using optical absorption and fluorescence emission techniques. Silver nanoparticles of different sizes
have been prepared by Creighton method using magnetic stirrer and ultrasonic field. Quenching of fluorescence of DHDMAQ has
been found to increase with decrease in the size of the silver nanoparticles. Stern–Volmer quenching constants have also been
calculated. |
