Unrevealing the opto-structural features of luminescent polymeric films containing Eu^III-doped phosphors through spectroscopic and theoretical perspectives

Abstract

Tailoring the opto-structural properties of lanthanide (LnIII)-doped phosphors dispersed in polymeric matrices through classical spectroscopic characterization is challenging due to their composite nature. To overcome this issue, a combination of...

Crystal growth, first-principles calculations, and enhanced 1.5–1.7 μm fluorescence emission from the Er, Ce: CaGdAlO4 laser crystal

“…Based on the obtained stable structure, the local geometrical information, and electronic and optical properties of rare earth ions in the matrix materials can be obtained by combining the luminescence principle with the first-principle calculations. [37][38][39][40][41][42][43][44][45][46][47][48][49][50] In this work, a series of Er, Ce: CGA crystals with different Ce 3+ ion doping concentrations were successfully prepared via the laser heated pedestal growth (LHPG) method. The mechanism of the structure-luminescence relationship was investigated.…”
