Photon avalanche upconversion and pump power studies in LaF3:Er3+/Yb3+ phosphor

Hexagonal LaF 3 :Er 3+ /Yb 3+ phosphor material has been synthesized by chemical precipitation method to obtain high near-infrared to green upconversion (UC) efficiency. Its thermal, structural and fluorescence properties have been studied. UC emission bands have been observed up to 315 nm in UV reg...
