This work reports on the fabrication route of electrospun fluoropolymer mats containing CsPbBr3 NPs. The samples have characterized by TEM and PL spectra. This work is interesting. I recommend for publication after minor revision.
Comments:
- Please check the Figure number in the manuscript. It seems misplaced. For example, As …..one can see from the SEM images presented in Figure 1 (e), the mats consisted of ~200 nm thick fibers…..
- It is recommended to include XRD patterns of respective NPs.

Reviewer 2 Report
Manuscript ID: nanomaterials-1098522Type of manuscript: ArticleTitle: Recrystallization of CsPbBr3 Nanoparticles in Fluoropolymer Nonwoven Mats for Down- and Up-Conversion of LightAuthors: Vladimir Neplokh *, Daria I. Markina, Maria Baeva, Anton M. Pavlov, Demid A. Kirilenko, Ivan S. Mukhin, Anatoly P. Pushkarev, Sergey V. Makarov, Alexey A. SerdobintsevSubmitted to section: Nanophotonics Materials and Devices The paper is concerned with a new method of preparation of nano CsPbBr3 particles inside electrospun polymer fibers: recristallization of dissolved CsPbBr3 nanoparticles in the polymer-Cs-Pb-Br precursor solution.The CsPbBr3 nanoparticles in the non woven mats produced show luminescence, up-conversion of IR and down conversion of UV light. These properties are technologically interesting and the industry friendly new fabrication method is highly attractive. The fibers and theire optical and stability properties are characterized well by photographs under UV and IR illumination, SEM and TEM, PL spectroscopy, and as stability test time dependent PL over 5 hours of fresh samples and again of the same samples after being stored for 1 week. The paper is written well, minor changes are required: 1. Extend the literature review of research on nanoparticles of CsPbBr3 in fibers in the introduction. A quick look into web-of-science brought up the following citations, that should be checked if appropriate to be mentioned:

- Figure 1: in 1 f) there is not much to see. If the single small bright dot in the center of the grey mat is meant as the one upconverting particle, add an arrow pointing to this particle. If something else is meant, make clear what.
- On page 4 last §: Do you really mean (Figure 2f) and (Figure 2e), or should it read (Figure 1f) and (Figure 1e).
- Figures 2a),b),c) are never discussed in the text.
- Page 5 last line is: the fitting of the obtained curves using Gauss functions
Change to: the fitting of the obtained luminescence line shape using Gauss function
- Figure 3b) is never mentioned in the text
- Line 196 is: Interestingly, upon immersion into water, the PL signal in-creases up to 44%
7a) change to: Interestingly, upon immersion into water, the PL signal in-creases up to 44% compared to the dry mats.
7b) show non normalized intensities that demonstrate the 44% increase.
- Conclusion line 211-212: “no degradation of luminescent properties was observed due to nonwoven mats deformation”.
This is a new result that has not been mentioned nor supported by data in the results part. New results must not appear or be mentioned in the conclusion. Shift to results part and show data, which allow to conclude this statement.

Reviewer 3 Report
This manuscript presents the effect of recrystallization of inorganic halides perovskite nanoparticles for down- and up-conversion of light. The authors showed some experimental results on down- and up-conversion of light from CsPbBr3 nanoparticles, however, there are many missing information. First of all, there are very weak analysis for recrystallization of nanoparticles. In addition, size distribution of perovskite nanoparticles are provided only in calculation. Single value of PLQY (without any supporting information) is insufficient for characterizing the nanoparticles. It is hard to distinguish whether the obtained PL intensity is due to down-conversion or down-shifting.
