An Innovative Approach to Design a Sensor for Environmental Hazardous Waste Management Using L-Alanine reinforced with Diglycine Picrate (LADGP) Crystal

Abstract

L-Alanine Diglycine Picrate (LADGP) single crystals were successfully grown at room temperature using the slow evaporation solution growth technique. The optical properties of the grown crystals were studied using UV–Vis–NIR spectroscopy, revealing good optical transparency in the visible region. The electrical properties were examined through dielectric and conductivity measurements, indicating favorable dielectric behavior. The laser damage threshold (LDT) study demonstrated that the LADGP crystal possesses a high resistance to laser induced damage, suggesting its suitability for laser-related and optoelectronic applications. In addition, picrate ions are known for their strong affinity toward binding organic compounds and heavy metal ions, and the crystalline structure of diglycine picrate provides a stable matrix with a relatively high surface area advantageous for adsorption processes. By incorporating L-alanine into the diglycine picrate lattice and optimizing the growth conditions at different pH values, the material’s adsorption capacity, stability, and selectivity can be enhanced. These characteristics indicate that LADGP crystals have potential not only in optical applications but also as promising candidates for hazardous waste treatment and environmental remediation.
