摘要：

We investigated the photoluminescence property of SrZrO3 nanocrystals synthesized by the using combustion method and varying the degree of crystallinity by using high-temperature annealing. In contrast to the bulk case, the SrZrO3 nanocrystals were found to show a strong violet-blue emission even at room temperature. As the crystallinity was enhanced and the grain sizes of the nanocrystals were increased, the violet-blue emission was gradually suppressed. This behavior implies that crystalline disorder is the main origin of the violet-blue emission from SrZrO3 nanocrystals.
