Optical Investigations in Er³⁺/Yb³⁺ Co-Doped Nanostructured Phosphate Glass Ceramics

Abstract:

Er³⁺/Yb³⁺ co-doped transparent phosphate glass ceramics were fabricated and characterized optically. The formation of nanocrystals is confirmed by x-ray diffraction. Stark split near infrared emission peaks of Er³⁺ have been observed in the glass ceramics, and the effective bandwidth increases with increasing annealing temperature. Upconversion emissions of Er³⁺ in the glass ceramics under 975nm wavelength excitation, especially in the green wavelength region, are enhanced. The results can be attributed to the enhancement of ligand field due to incorporation of Er³⁺ ions into the crystal lattices.
