Abstract

Lutetium based oxyorthosilicate (Lu2SiO5:Ce3+/Lu2−xYxSiO5:Ce3+) and pyrosilicate (Lu2Si2O7:Ce3+) scintillators exhibit good scintillation performances in terms of light-yield and decay properties. Nevertheless, both of them have a high melting point (≥1900 °C) which is unfavorable to crystal growth. In this work, an alternative lutetium based silicate scintillator was proposed with a lower melting point (about 1500 °C): Na3LuSi3O9:Ce3+. The structure and thermal quenching properties of Na3LuSi3O9:Ce3+ were investigated. The emission spectra of Na3Lu0.99Ce0.01Si3O9 under UV and X-ray excitation as well as pulsed X-ray measurements were also determined. The phosphors show a broad emission band from 320 nm to 475 nm. Due to the suitable emission wavelength range, the fast decay properties and relative low melting point, Na3LuSi3O9:Ce3+ may be a potential novel inorganic scintillator material.
