Reviewer 1 Report
In this work, Ce doped GdYAlGa garnet transparent ceramics were obtained with different Ce concentrations and the luminescence properties were studied by scanning confocal microscopy. Some interesting results were obtained. However, the author's conclusion based on the experimental results are overly speculative. More works are needed to be done to enhance the scientific soundness of the work.
1. The information of obtained powder with different Ce should be given, such as phase composition, crystal size etc.
2. How about the transparency of the samples? The light transmission curve is suggested to be given.
3. The mechanism of Ce4+ promotion on grain growth should be discussed.
4. The ratio of Ce3+/Ce4+ of samples with different Ce concentrations should be measured and shown in the work.
5. The author claimed that the distributions of Ce ions at the grain boundaries and in the grains are different. EDS mapping is suggested to be performed on these samples.
