N1 - The work was supported by state assignment of IGM SB RAS No. 122041400031-2. Spectroscopic studies were carried out within the framework of state task No. 0350-2016-0024 \"Crystalline and amorphous functional materials with predictable properties\" (Vinogradov Institute of Geochemistry SB RAS). Crystal growth technique and synthesis methods were adopted under grant of Russian Science Foundation No. 23-19-00617. The X-ray Diffraction Centre and Geomodel Center of Resource Centre of Saint Petersburg State University provided instrumental and computational resources (grant SPbU ID 116234388).

N2 - A series of novel KSrY1–xErx(BO3)2 (x = 0–1) phosphors that emit near-infrared radiation was synthesized using solid-state methods. Pure Y and Er crystals were grown using a KF flux via the top-seeded solution growth technique. In situ high-temperature single crystal X-ray diffraction, Raman spectroscopy and DFT calculations were used for characterization. Within the series, a polymorphic phase transition from space group P21/m to R3m was discovered between 550 and 600C. The concentration dependence of the luminescence intensity was measured for the samples. A strong emission of Er3+ electron transition 4I13/2 ! 4I15/2 was detected within the 1529–1549 nm range, with the maximum observed for the KSrY0.4Er0.6(BO3)2 composition.
