dc.description.abstract | This study considers effects of pressure of up to 110 kbar on line position and fluorescence lifetime T for T-4(1) - GT (6)A(1) transition in LMA:Mn2+ and LMA:Mn2+, Nd3+. Energy transfer between Mn2+ and Nd3+ in LMA:Mn2+, Nd3+ has also been considered. Results indicate pressure induced line shift towards longer wavelengths, a red-shift in both crystals with the same rate of 0.182 nm kbar(-1). Pressure influences fluorescence lifetime T in the considered crystals differently; whereas for LMA:Mn2+ increasing pressure causes slow linear decrease Of T, and for LMA:Mn2+, Nd3+ T increases linearly as pressure raises. Energy transfer efficiencies decrease with pressure. High pressure induced red-shift can be explained by a simple model. (c) 2007 Elsevier B.V. All rights reserved. | en |
