The article entitled “Broadband Laser Protection and enhanced Nonlinear Optical Response of Samarium-Metal–Organic Framework Based White/Black Carbon Hybrids” presents the broadband nonlinear optical response of Sm-MOF, Sm-MOF/BN, and Sm-MOF/rGO hybrids. By Z-scan experiment with varying excitation wavelengths of picosecond laser pulses, the nonlinearity of hybrids was well demonstrated. There are few suggestions to be addressed and they are,
1. What is the bandgap of the materials? Include the information for analysing the multi-photon absorption.
2. Theoretical fit to the samples is to be rechecked. Especially the fits of higher wavelength need to be redrawn.
3. Information on the experimental parameters of Z-scan such as Rayleigh range, Beam waist as a function of wavelength need to be included for readers clarity.
4. In open aperture, the nonlinear absorption coefficient increases with wavelength, from 700 nm to 1000 nm. Clarify.
5. Demonstration of wavelength dependent nonlinear absorption and its possible mechanism of three photon absorption shall be included. Refer to ACS Applied Nano Materials 1, 11 (2018), 6337-6348, Optical Materials 66 (2019) 534-541, Journal of Applied Physics 124, 19 (2018).
6. Comparison of NLO coefficients with other composites excited under similar condition shall be more included.
So, I recommend the article for MINOR revision.

In the revised article entitled "Broadband Laser Protection and enhanced Nonlinear Optical Response of Samarium-Metal–Organic Framework Based White/Black Carbon Hybrids”, the author has answered all the queries raised by the reviewers satisfactorily. So, I recommend the article for publication.
