Structural and Optical Properties of Nd<sup>3+</sup> Doped Na<sub>2</sub>O-PbO-ZnO-Li<sub>2</sub>O-B<sub>2</sub>O<sub>3</sub> 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 Nd 3+ doped sodium lead zinc lithium borate glass. The glasses with chemical formula (65-x)B 2 O 3 -15Na 2 O-10PbO-5ZnO-5Li 2 O-xNd 2 O 3 (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 4 I 9/2 → 2 G 7/2 + 4 G 5/2 . 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 4 F 3/2 → 4 I 11 /2 transition obtained when Nd 3+ ion content in the borate glass is 1.0 mol %. It is indicating that Nd 3+ doped borate glass have self-quenching or concentration quenching.
