Abstract: Abstract KLa(MoO4)2:Yb3+/Ho3+ phosphors were synthesized using hydrothermal method. The phosphors showed intense green (∼546 nm) and weak red emissions (∼651 nm, ∼756 nm) by 980 nm excitation. Temperature-dependent fluorescence intensity ratios (FIRs) are analyzed. The… read more here.

DOI: 10.1016/j.materresbull.2020.111079
Abstract: Abstract Square-like KLa(MoO4)2: Yb3+/Er3+ mono-disperse crystals were synthesized by hydrothermal process. Their up-conversion luminescence (UCL) emissions were contributed by green (2H11/2/4S3/2 → 4I15/2) and red light radiation (4F9/2 → 4I15/2) transitions of Er3+ under 980… read more here.
