Z-scan screening of proton-shifted monohydrated organic salt: the linear, nonlinear, and optical limiting characteristics for photonic applications

Abstract

In the present decade, the advancement in photonic applications has stimulated the scientific community to explore nonlinear optical characteristics of optical materials. The present report on the synthesized proton-shifted monohydrated organic salt (ABMPP) of 2-Amino-5-bromo-6-methyl-4-pyrimidinol (ABMP) and 2,3-pyrazinedicarboxylic acid (PDCA) explores the linear and nonlinear optical (NLO) characteristics. The linear optical characteristics of ABMPP dissolved in DMSO have been investigated using the recorded absorption and photoluminescence spectra. In addition, the 1H-NMR analysis has been executed for structural characteristics. The third-order nonlinear optical characteristics of the sample have been measured using the Z-scan technique with a 520 nm laser beam of CW diode laser. The coefficients of nonlinear absorption (β), nonlinear refraction (n2) with nonlinear optical susceptibility, χ(3), and second-order hyperpolarizability (γ) have been estimated for various solution concentrations and laser powers. The evaluated β, n2, χ(3), and γ are found to be of the order of 10−4 cm/W, 10−8 cm2/W, 10−6 esu, and 10−26 esu, respectively, and these parameters vary linearly with solution concentration as well as laser power. The NLO performance of the ABMPP compound reveals its potential in photonic and optoelectronic applications. Furthermore, the compound has been also assayed for optical limiting characteristics with the same radiation and it shows comparatively better limiting performance. Hence this material could be a viable candidate for optical limiting devices.
