| 抄録: | Deep red persistent luminescence properties of Cr³⁺ activated LaAlO₃ phosphors were investigated. The variation of lanthanide codopants, Sm³⁺, Eu³⁺, Tm³⁺ on thermoluminescence (TL) glow curves suggests an electron trap model of persistent luminescence in LaAlO₃: Cr³⁺ phosphors. Between lanthanide cations, Sm³⁺ was found to be a good codopant for enhanced persistent luminescence. TL excitation spectrum showed only a UV band similar to that of photoluminescence excitation which are attributed to ⁴A₂→⁴T₁(⁴P). Based on the structure and intensity of TL glow curves after different wavelength excitation, it is found that the efficient charging through conduction band and inefficient local charging occur under UV and blue excitation, respectively. |
