Structural and Optical Properties of Nd3+ Doped Na2O-PbO-ZnO-Li2O-B2O3 Glasses System

Abstract

The present paper reports the structural (XRD and FTIR spectra), physical (like density, molar volume, refractive index etc.), optical absorption and emission properties of Nd3+ doped sodium lead zinc lithium borate glass. The glasses with chemical formula (65-x)B2O3-15Na2O-10PbO-5ZnO-5Li2O-xNd2O3 (where x = 0, 0.05, 0.1, 0.5, 1.0, 2.0 and 4.0) have been prepared using the melt-quenching method. XRD characterization shows that the glasses are amorphous nature. The values of measured absorption transitions obtained ten transitions and the hypersensitive transition at 4I9/2 → 2G7/2+4G5/2. To excite photon from ground state to upper state, used two different wavelength spectra at 582 and 804 nm. The maximum emission intensity of the 4F3/2 → 4I11/2 transition obtained when Nd3+ ion content in the borate glass is 1.0 mol %. It is indicating that Nd3+ doped borate glass have self-quenching or concentration quenching.
