We experimentally verify that a color center in the form of Se2- takes shape in silicate glasses containing relatively small amount of ZnSe which are prepared via a conventional melt-quenching process. Samples also produce broad photoluminescence when excited with UV light source, suggesting potential applications in the visible range. Analyses based on X-ray diffraction patterns, high resolution transmission electron microscopy, and Raman spectroscopy support the formation of Se2- color centers in addition to Se nanocrystals.
► We synthesized silicate glasses varying ZnSe content. ► Visible emission was observed when pumped with UV-light source. ► XRD, HR-TEM and Raman analyses were performed. ► Analysis proved the formation of Se2- color centers along with nanocrystals.
