| description | This work is dedicated to the growth process and investigation of luminescent and scintillation properties of CeAlO<sub>3</sub> single crystals and CeAlO<sub>3</sub>/CeAl<sub>11</sub>O<sub>18</sub> metamaterials under e-beam and α-particles excitation. It has been shown that cathodoluminescence and radioluminescence spectra of CeAlO<sub>3</sub> crystals contain two bands, peaking at 440 and 500 nm, and caused by the Ce<sup>3+</sup> 5d−4f transitions into CeAl<sub>11</sub>O<sub>18</sub> phase, which is present in these crystals as an admixture. Under 270 nm ultraviolet (UV) light excitation, a CeAlO<sub>3</sub> crystal possesses complicated non-exponential luminescence decay, with the average decay time of 16 ns. The light yield of CeAlO<sub>3</sub> crystals under α-particle excitation is about 16% and 12%, in respect to the standard Bi<sub>4</sub>Ge<sub>3</sub>O<sub>12</sub> (BGO) crystal and Y<sub>3</sub>Al<sub>5</sub>O<sub>12</sub>:Ce (YAG:Ce) single crystalline film samples, respectively. The CeAlO<sub>3</sub> scintillation decay is quite fast, with the decay time value t<sub>1/e</sub> in the 54−56 ns range. |
