N2 - A novel one-step method of preparing Y2O2Se from Y2O3 and Se in a CsCl flux is reported. Pure Y2O2Se and Y2O2Se:1%RE3+ solid solutions were quantitatively prepared and studied. The Y2O2Se sample is stable in air up to 680°C and has a melting point of 2015ºC in an inert atmosphere. Optical properties of Y2O2Se:1% RE3+ samples (RE=Ce – Nd, Sm, Eu, Tb – Yb) were investigated.
