High Yield Luminescence of Lanthanide J‐Levels in Fluoride Glasses with Weak Multiphonon Relaxation

Abstract

Glasses prepared from mixed fluorides containing trivalent lanthanides show a unique propensity to luminescence of a given J‐level, if the distance to the closest lower J‐level is at least 2,000 cm−1 (to be compared with 5,000–10,000 cm−1 in most other materials).

Developments in Luminescence and Display Materials Over the Last 100 Years as Reflected in Electrochemical Society Publications

“…They reported a resonant energy transfer from the 1 D 2 Tm 3ϩ state to the 5 D 4 Tb 3ϩ state. Jorgensen et al 161 found high yield luminescence of lanthanide J-levels in fluoride glasses with weak multiphonon relaxation.…”
