Origin of Thermal Degradation of Sr2–xSi5N8:Eux Phosphors in Air for Light-Emitting Diodes
Chiao Wen Yeh,Wei Ting Chen,Ru-Shi Liu,Shu Fen Hu,Hwo-Shuenn Sheu,Jin-Ming Chen,Hubertus T. Hintzen +6 more
TL;DR: The origin of the thermal degradation in Sr(2-x)Si(5)N(8):Eu(x) with x = 0.10 is due to the formation of an amorphous layer on the surface of the nitride phosphor grain during oxidative heating treatment, which results in the oxidation of Eu ions from divalent to trivalent.

Color Tuning Luminescence of Ce3+/Mn2+/Tb3+-Triactivated Mg2Y8(SiO4)6O2 via Energy Transfer: Potential Single-Phase White-Light-Emitting Phosphors
TL;DR: In this paper, the dual energy transfer from Ce3+ to Mn2+ in Mg2Y8(SiO4)6O2 (MYS) oxyapatite phosphors has been demonstrated to be a resonant type via a dipole-quadrupole mechanism, and the critical distance calculated by quenching concentration method and spectral overlap method are 10.5 and 9.7 A, respectively.

Single-composition trichromatic white-emitting Ca4Y6(SiO4)6O: Ce3+/Mn2+/Tb3+ phosphor: luminescence and energy transfer.
TL;DR: The studied results indicate that the as-prepared CYS: Ce(3+), Mn(2+), Tb(3+) phosphors have good CL intensity and CIE color coordinate stability with a color-tunable emission crossing the whole white light region under low-voltage electron beam excitation.
