“…Based on these, we suggested that the luminescence originate from the structure defects or surface states of SrZrO 3 nanocrystals. The luminescence originating from defect centers is very common, such as in SrTiO 3 , TiO 2 , SrAl 2 O 4 and so on [13][14][15]. The SrZrO 3 structure (see Fig.…”

“…However, with an increased in the calcination temperature at 750 • C the formation of ZnO remains suppressed completely and a single phase of crystalline willemite β-Zn 2 SiO 4 has been obtained. This implies the nucleation temperature of willemite phase [19]. [20].…”

“…Some other articles describe a broad band emission with maximum at about 450 nm [9]. In one article sharp lines in the photoluminescence spectrum were observed [10], not characteristic for a solid material intrinsic defects, it seems the source of these lines might be some trace amount of transition metals or rare earths present in the material. As for different excitation sources -a broad, possibly complex, band luminescence revealing 450 and 500 nm maxima has been re-ported under X-ray irradiation [11] [12], that in our opinion could be the luminescence of SrAl2O4 intrinsic defects, however these bands are close to those known for Eu 2+ in this material.…”
