| dc.description | Rare earth silicate based MnMgSi2O5+n (M = Ca, Sr or Ba and n=1-2) phosphors, have
attracted interest of researchers due to their high efficiency as a host, excellent thermal and
chemical stability and high brightness adding to their low cost. These phosphors showed great
potential in various applications such as fluorescent lamps, white light emitting diodes, and display
components. High temperature solid-state reactions are usually employed to synthesize those
compounds. This paper proposes an alternative method of obtaining nanophosphor host based on
Eu-doped CaMgSi2O6 (CMS:Eu), persistent luminescence phosphor. Sol gel technique combined to
a modified molten salt method was used. The resulted powder was calcined for 3h under an
atmosphere of 5% H2 and 95% Ar2. Phase identification by XRD and the measurements of
photoluminescence (PL) and photoluminescence excitation (PLE) were performed. Single phased
CMS:Eu with persistent luminescence characteristics was prepared. | |
