In this work a new methodology to synthesize strontium selenide on the base of reduction of selenium is presented. The selenium comes from oxidation stage 0 to -2, afterward it is mixed with a strontium salt, strontium chloride. In this process a fast substitution of chemical reaction is realized. In order to make the optical characterization, the adsorption in the UV-visible range was measured leading to compute direct and indirect band gap energies. The obtained strontium selenide is a black powder dispersed in aqueous solution, the obtained Band gap values were 5.19 and 4.53 eV for direct and indirect respectively. From the Raman spectrum was identified three peaks: at 114 and 234 cm-1corresponding to strontium selenide, and 456 cm-1corresponding to strontium oxide. The infrared response shows Sr2+at 524 cm-1, strontium oxide at 615 cm-1plus O-H vibration and bending vibration H-O-H. Finally from transmission electron microscopy a crystalline structure was found.
