Growth and Scintillation Properties of Na⁺-Doped CsCu₂I₃ Single Crystals

Round 1

Reviewer 1 Report

Comments and Suggestions for Authors

Change the title, please. "the prepared" is not appropriate for tasks involving crystal growth.

The article's English may require some improvement. By including the relevant information, such as heating rate, translation rate, and furnace specifications, the experimental portion of crystal growth should be improved.

Since these crystals are well-known, the phrase "for the first time" should be removed from the conclusion because adding dopant to them does not make them novel.

Comments and Suggestions for Authors

In this article, a new scintillator crystals is synthesized, and some of its properties are studied depending on the dopant concentration. There is no doubt that new, effective scintillators are a necessity. However, there are a number of comments and questions about the article:

-In Fig. 1-6 need to increase the resolution (it looks a bit blurry);

-In the section of the experimental procedure, there is no indication of the error of the instruments used;

-Reference [7] lacks output;

- The text of the article does not indicate the reason for choosing the stoichiometry of the grown CsCu₂I₃ single crystal;

- Has the scintillation properties of single crystals and powders been compared?

-The title of the article [17] from the list of references states that for pure CsCu₂I₃ PLQY=15.7%. On Fig. 4c, the authors show a measured value of 9.9%. What is the reason for this difference?

-For CsCu₂I₃:Na (3%) crystal tau1=91.x ns?

-According to the research results, we can say that 3% Na is the "threshold concentration". Have any studies been carried out on crystals with a smaller doping step near this value? Is this "threshold value" confirmed by other methods (unit cell parameters, vibrational spectroscopy)?

-Has there been a comparison of the properties of crystals cut from different parts of the boule?

-In the sentence on lines 35–38, there is an extra point.

-Line 131 says "lambda_em=580 nm". For CsCu₂I₃:Na crystals, lambda_em=575 nm, and for CsCu₂I₃ crystal lambda_em=570 nm, according to [3] from the list of references. It is necessary to eliminate the contradiction.

-What does [J] mean in the bibliography?

-There is a special symbol for the diameter in the Word editor. There is no need to use the Russian letter "Ф".

Reviewer 2 Report

Comments and Suggestions for Authors

The authors have significantly improved the text of the article. However, there are a few minor remarks:

-Ref 8 is a dissertation? If yes, please indicate it.

-I couldn't find references 19 and 21 cited. Reference 16 is cited at the very end, not in order of appearance.

-In reference 12, it is necessary to correct the subscripts.

-In line 98, there is a link to fig. 1d, but there is no such figure in the text.
