Abstract

A series of Sr-Si-S compounds was synthesized using an advanced chemical method in which the use of one solution-based process uniformly dispersed the Eu²⁺ activators in the host crystals, to find new compositions that would suit phosphor applications. Particular focus was given to the Si-rich region. This led to the synthesis of a single-phase compound that showed an unknown X-ray diffraction pattern. This compound had a composition close to that of SrSi₂S₅. When this compound is activated with Eu²⁺ (SrSi₂S₅:Eu²⁺), it shows a cyan-blue emission with a main luminescence peak at 495 nm. This emission is excited by wavelengths of 250–440 nm and has a maximum excitation at 350 nm.
