Optical and X-ray-induced Luminescence Properties of Calcium Phosphate of Transparent Ceramic Form [PDF]

(Received December 18, 2019; Accepted March 2, 2020)

Keywords: transparent ceramic, calcium phosphate, luminescence properties, SPS

Undoped and Sb-doped calcium phosphate transparent ceramics were prepared by the spark plasma sintering (SPS) technique, and their optical and X-ray-induced luminescence properties were investigated. As optical properties, the transmittance of the undoped transparent ceramic with a thickness of 1.05 mm reached a value higher than 50% in the range of 500-2500 nm. The undoped calcium phosphate exhibited an emission peak at 450 nm due to excitons. On the other hand, the Sb-doped calcium phosphate showed a broad emission peak attributable to the 3P1-1S0 transitions of Sb3+ ions around 500 nm in both PL and scintillation spectra. The obtained scintillation decay time constants of the 0.1% Sb-doped calcium phosphate were 1.2 and 7.9 μs. Glow peaks were detected at 90, 160, and 360 °C. The TSL intensity decreased with the increase in Sb concentration.
