Abstract

A bluish-green color long-lasting phosphorescent phosphor of N contained Ba₂SiO₄:Eu²⁺ for X-ray and cathode ray tubes are prepared with the chemical component formula Ba₂SiO ₄:0.01Eu²⁺- x-Si₃N₄ - 2BaCO ₃ (x = 0.1 to 1.0) by the conventional high-temperature solid-state method. The phosphorescence and fluorescence properties as a function of Si ₃N₄ content and temperature are investigated. The emission spectra show a single broad band peaking at 505 nm, which are ascribed to the 4f⁶5d¹ → 4f⁷ transition of Eu ²⁺. Thermoluminescence (TL) glow-curves show that Ba ₂SiO₄:0.01Eu²⁺ without N holds a high-temperature peak at 417 K. With increasing the content of Si ₃N₄, the phosphorescence grows super-linearly and some new TL peaks appear at low temperatures of about 400, 355, 365, and 335 K. These peaks are ascribed to the formation of new traps related to N substitution for O.
