Nanosized (Y1−xGdx)2O2S:Tb3+ particles: synthesis, photoluminescence, cathodoluminescence studies and a model for energy transfer in establishing the roles of Tb3+ and Gd3+ [PDF]

open access: yesRSC Advances, 2016
Herein we describe the synthesis and spectral analysis of nanosized (Y1−xGdx)2O2S:Tb3+ phosphors between x = 0 and x = 1 with 0.1 and 2 mol% Tb3+. The concentration of Gd3+ was varied in steps of 0.1 (mole ratio Gd3+).

The Use of Y3Al5O12:Ce3+ and CaTiO3:Pr3+ in a Dual-layer Remote Phosphor Configuration Improves the Optical Efficiencies of a Phosphor-in-Glass White Light-Emitting Diode

open access: yesJournal of Advanced Engineering and Computation, 2022
Although distant phosphor structure is not the best choice for color fidelity of white-light-emitting diode (W-LED) sources, it benefits the luminous flux of LED more than conformal or in-cup phosphor models.

Re-Absorption Effect Modeling for Dual-Layer Phosphor Package of White LEDs

open access: yesIEEE Photonics Journal, 2021
This paper successfully establishes an optical model with dual green/red phosphor layers based on the original single-phosphor model. Since the re-absorption effect of double-layer phosphors causes spectral distortion, the model must introduce a ...
