Abstract
Enhanced luminescence properties of Malachite Green (MG) (oxalate) in Fe-MG codoped SiO2glasses compared to its values in MG doped SiO2glasses are reported here. The enhancement is chiefly attributed to a resonance nonradiative energy transfer between Fe and MG. The quantum yield of Malachite Green (MG), in presence of Iron, trapped in sol-gel derived SiO2glass increases by an order of ~103compared to that in low viscous solvent while a lifetime of 3.29 ns is reported.
