Abstract:Through conventional solid-state sintering process, PbNb2O6:Yb3+, Ln3+ (Ln3+=Er3+/Ho3+)
ceramics have been fabricated. The structural information of synthesized ceramics was
obtained via X-ray diffraction. Scanning electron microscopy was utilized to investigate
their morphological properties. The investigation of upconversion photoluminescence
properties of the synthesized ceramics was conducted by analyzing upconversion emission
spectra upon excitation with 980 nm light. Power dependence studies confirmed th… Show more
