| 抄録: | Cr³⁺-activated Y₃Al₂Ga₃O₁₂ garnet (YAGG:Cr³⁺) persistent phosphor has been recently reported as a potential candidate material for in vivo imaging application. Temperature dependence of photoluminescence (PL) spectra and thermostimulated luminescence (TSL) glow curves with several conditions, especially photostimulation wavelength dependence, were carefully investigated with the perspective of deep trap utilization for long-term in vivo imaging. The PL spectrum showed typical Cr³⁺ emission due to ²E→⁴A₂ and transitions) does not suffer from temperature quenching up to 600 K. From the TSL glow curve measurements, it was found that the persistent luminescence cannot be activated by visible light excitation. However, photostimulation induced persistent luminescence by red to near-infrared light can be possible in this material. |
