Silver nanoclusters (NCs) embedded in soda-lime glass was synthesized by the electric fieldassisted diffusion (EFAD) and successive annealing.The samples were characterized by UV-Vis absorption spectroscopy,photoluminescence spectroscopy,X-ray photoelectron spectroscopy (XPS),and lifetime measurements.The experimental results show that the growth of silver clusters is favored by the annealing temperature and dwell time.The as-diffused and annealed glass samples show photoluminescence around 550 nm under UV excitation,which can be associated with the presence of L-center and Ag3+ cluster.And the increasing of the annealing temperature and dwell time results in an appearance of the SPR peak and the decreasing of the luminescence intensities because the Ag3+ clusters grow up into the Ag nanoparticles.
