Abstract

The influence of silver nanoparticles on Er³⁺ up-conversion in CaF₂ precipitated oxyfluoride glass-ceramics is investigated. After heat-treatments, transmission electron microscopy images show that CaF₂ nanocrystals precipitate in the glass matrix uniformity, and sliver nanoparticles are spread around the CaF₂ nano-crystals simultaneously. Comparing with the samples without Ag doped, high efficiency up-conversion luminescences of Er³⁺ at 540 and 658 nm are distinctly observed in the silver nanoparticles containing glass-ceramics by the 980-nm excitation. Moreover, since the intensity ratio of green and red emissions changes after silver nanoparticles precipitation, the up-conversion mechanism of Er³⁺ is discussed.
