Structural and Luminescence Properties of Yellow-Emitting NaScSi2O6:Eu2+ Phosphors: Eu2+ Site Preference Analysis and Generation of Red Emission by Codoping Mn2+ for White-Light-Emitting Diode Applications
TL;DR: In this article, the structural properties of clinopyroxene NaScSi2O6 have been investigated using the X-ray powder diffraction refinement, and the luminescence properties of Eu2+ and Eu 2+/Mn2+-activated NaSc SiO6 has been studied to explore the new materials for phosphor-converted white light ultraviolet light-emitting diodes (UV-LEDs).

Chemical Unit Cosubstitution and Tuning of Photoluminescence in the Ca2(Al1–xMgx)(Al1–xSi1+x)O7:Eu2+ Phosphor
Zhiguo Xia,Zhiguo Xia,Chong-Geng Ma,Maxim S. Molokeev,Quanlin Liu,Karl Rickert,Kenneth R. Poeppelmeier +6 more
TL;DR: The concept of "chemical unit cosubstitution" is described as one such potential design scheme that enables the tuning of luminescent properties in phosphor materials and is shown to be restricted to tetrahedral sites.

Linear structural evolution induced tunable photoluminescence in clinopyroxene solid-solution phosphors
TL;DR: The spectroscopic properties of (Na1−xCax)(Sc1+xMgx)Si2O6 clinopyroxene solid-solutions are in direct relations with structural parameters, and it is helpful for designing color-tunable photoluminescence with predetermined parameters.
