Structural phase transitions and photoluminescence properties of oxonitridosilicate phosphors under high hydrostatic pressure Agata Lazarowska1, Sebastian Mahlik1, Marek Grinberg1, Guogang Li2,3 & Ru-Shi Liu2,4 Spectroscopic properties of a series of (Sr0.98-xBaxEu0.02)Si2O2N2 (0 ≤ x ≤ 0.98) compounds has been studied under high hydrostatic pressure applied in a diamond anvil cell up to 200 kbar. At ambient pressure the crystal structures of (Sr0.98-xBaxEu0.02)Si2O2N2 (0 ≤ x ≤ 0.98) are related to the ratio of strontium to barium and three different phases exists: orthorhombic Pbcn(0.78 ≤ x ≤ 0.98), triclinic P1 (0
