A Novel Synthesis Method of Dumbbell-like (GdTb)O(CO)·HO Phosphor for Latent Fingerprint.

A novel method for synthesizing dumbbell-shaped (GdTb)O(CO)·HO (GOC:Tb) phosphors using sodium carbonate was investigated. An amount of 1 mmol of stable fluorescent powder can be widely prepared using 3-11 mmol of NaCO at a pH value of 8.5-10.

Fixed Yellow-to-Blue Intensity Ratio of Dy in KY(CO) Host for Emission Color Tuning.

Dy, Ce co-doped KY(CO) phosphors with a monoclinic structure were synthesized using the hydrothermal method to create a fixed yellow-to-blue ratio emission. The [YO] polyhedron, consisting of a Y atom and eight oxygen atoms, forms a relatively independent microstructure within the KY(CO) host. Y ions are partially replaced by Ce or Dy ions to construct the [CeO] or [DyO] polyhedral fluorescence emission unit.
