Description

In this research work, we prepared SmI2 anhydrous hydrate rare-earth iodides by using an eco-friendly Annealing technique using He or H2 furnance for vaccum dehydration. To develop and apply these scintillators effectively, it is crucial to have an efficient and economical method to produce high-purity Samarium di-iodide (SmI2). We conducted a comparative study on the dehydration mechanisms of SmI2 hydrate and its mixture with HI using I-V and fluorescence spectroscopy. The photoluminescence excitation spectrum of Samarium di-iodide at 374nm is recorded and studied, because of their, luminescent features, most intensive peaks, and high color purity.The thermal decomposition process of individual Samarium di-iodide hydrate was found to be as SmI2, and we comprehensively studied the solution combustion mechanism. Samarium di-iodide is a strong electron reducing agent. The importance of SmI2 will be discussed.
Keywords: Samarium di-iodide , Rare-earth.
