Highly efficient upconversion of Er(3+) in Yb(3+) codoped non-cytotoxic strontium lanthanum aluminate phosphor for low temperature sensors
Er(3+) and Er(3+)/Yb(3+) melilite-based SrLaAl(3)O(7) (SLA) phosphors were synthesized by a facile Pechine method. The differences in emission intensities of (4)I(13/2) → (4)I(15/2) transition in NIR region when excited with Ar(+) and 980 nm lasers were explained in terms of energy transfer mechanis...
