Judd-Ofelt Analysis of Nd(TTA)3Phen-doped 6-FDA/Epoxy Planar Waveguides
The fluorescent complex Nd(TTA)3Phen (TTA = thenoyltrifluoroacetone, Phen = 1, 10-phenanthroline), was doped into the host material 6-FDA epoxy (6-fluorinated-dianhydride cured epoxy). The room-temperature absorption spectrum of Nd transitions was experimentally obtained, with which the Judd-Ofelt model was applied to determine the Judd-Ofelt parameters. These parameters are used to calculate t...
متن کاملCorrigendum: Lanthanide-Doped KLu2F7 Nanoparticles with High Upconversion Luminescence Performance: A Comparative Study by Judd-Ofelt Analysis and Energy Transfer Mechanistic Investigation
The development, design and the performance evaluation of rare-earth doped host materials is important for further optical investigation and industrial applications. Herein, we successfully fabricate KLu2F7 upconversion nanoparticles (UCNPs) through hydrothermal synthesis by controlling the fluorine-to-lanthanide-ion molar ratio. The structural and morphological results show that the samples ar...

متن کاملMicrostructure and optical properties of Pr3+-doped hafnium silicate films
In this study, we report on the evolution of the microstructure and photoluminescence properties of Pr3+-doped hafnium silicate thin films as a function of annealing temperature (TA). The composition and microstructure of the films were characterized by means of Rutherford backscattering spectrometry, spectroscopic ellipsometry, Fourier transform infrared absorption, and X-ray diffraction, whil...
