Abstract
A novel red light emitting nano-sized Eu3+ doped SrY1.7B0.3O4 phosphor were synthesized by combustion method using urea as a fuel. Comparing with traditional material processing techniques, combustion method is a relatively simple method. The advantages of low temperature solution base process have been exploited to produce SrY1.7B0.3O4:Eu nanoparticles. The nano crystals obtained through combustion method was characterized by using scanning electron microscopy (SEM), X-ray diffraction (XRD) technique and photoluminescence (PL) spectra. This red emission has been assigned to the transition [5D0 →7F2] at 612 nm of Eu3+ ions. In addition the dependence of the luminescence intensity on Eu3+ ions concentrations and effect of heat treatment on the particle size of the nanocrystals have also been discussed. The present work reports to achieve the homogenous incorporation of dopants and large scale productions of the nanophosphor in a short interval of time. The particle size of the nanocrystals was found to be in the range of 30-40nm.
