摘要	Expanded emission spectra ranging from green to red are reported in Ca3Sc2Si3O12 (CSS):Ce3+,Mn2+ silicate garnets. Mn2+ may occupy Ca2+ site (Mn2+(I)) to generate a yellow emission band at 574 nm or Sc3+ site (Mn2+(II)) with red emission band at 680 nm. Efficient energy transfers from the green emitting Ce3+ to both Mn2+(I) and Mn2+(II) occur upon blue excitation into Ce3+. Concentration dependence of Mn2+ emission is analyzed based on Ce3+-Mn2+ energy transfer, steady state rate equations, and fluorescence lifetimes. Energy transfer efficiency (eta(T)) and rate (W) are calculated with values as high as 45% and 14.01 x 10(6) s(-1), respectively. (c) 2011 Elsevier B.V. All rights reserved.
