Round 1
Reviewer 1 Report
- In this paper, λ/4-λ/4 double-layer antireflective (AR) coatings with constant high transmittance in a pre-determined wavelength range was proposed and prepared by sol-gel method via acid-catalyzed and base-catalyzed SiO2 thin films. A double-layer antireflective coating with an almost constant transmittance value of 99.8% in the range of 550–700 nm was obtained, and the transmittance of this coating was higher than 99% in a wide range of 450–850 nm with fluctuation less than 1%.
- In the figure 6, AFM 3D images of bottom layer coating should be demonstrated in detail.
- The manuscript has 10 pages; the length of the manuscript should be increased.
4.Please revise and enhance the English writing to increase readability.

Reviewer 2 Report
The authors reported the manuscript entitled "λ/4-λ/4 Double-layer Broadband Antireflective Coatings with Constant High Transmittance" nicely and in a well-organized way. Paper may be accepted after minor revision.
- Include the novelty and objectives of the study in the manuscript clearly.
- Include the name of manufacturers and country of chemicals used.
- Why the ratio of TEOS and MTES has no effect on the refractive indexes of mentioned films before calcination?
- Why the transmittances of the prepared double-layer broadband ARC were significantly enhanced as compared to that of bare glass?

Reviewer 3 Report
- At section 2.1, specify the concentration for TEOS, MTES and HCl.
- At section 2.2, specify the concentration of NH3H2O
- At 2.3, specify how the surfaces (BK-7 glass) were washed before use.
- Schematic representation of the sol-gel method to obtain the materials must be add.
- Specify the advantage of dip-coating method
- Macroscale images of the coating would be convenient.
