Abstract: By co-substituting a cation (M2+: Ba2+ or Ca2+) and Al3+–O2− into Sr2Si5N8:Eu2+ in a solid-state method, we successfully synthesized the nitrido-alumino-silicate phosphors Sr(2−y)MySi5−xAlxN8−xOx:Eu2+ (Ba-AlO-258 (My = Ba0.3, x > 0) and Ca-AlO-258 (My = Ca0.3,… read more here.

Abstract: One of the biggest problems in white light-emitting diodes (WLEDs) is the moisture-induced degradation of phosphors. This paper proposes a simple and feasible surface modification method to solve it, whereby a hydrophobic surface layer is… read more here.
