文摘
- •
Magnetic susceptibility data reveal a mictomagnetic type behavior.
- •
Both isolated and exchange coupled Nd3+ ions are present in the host glass ceramic.
- •
The metallic silver nanoparticles are excited by TPA mechanism.
- •
Metallic silver nanoparticles transfer energy to the neodymium.
- •
Upconversion phenomena are observed through some emission peaks.
