In this manuscript, the authors investigated the strong NLA and efficient broadband OL performance of Sm-MOF, Sm-MOF/BN and Sm-MOF/rGO hybrids over a wide wavelength range from 600 to 1000 nm. This paper might suitable for the publication on Nanoscale, but before publication, major and necessary revision should be made. More detail comments are as follows:

1. The language used in this study is one of its main issues. To ensure accuracy and precision, the entire content must be reviewed for language and grammar errors. I am not in a position to detail all of the errors, both minor and major, here. Like, the first sentence of the Abstract is not a complete sentence.
2. The XRD partern of reported compunds should be provided in SI.
3. The related peaks should be marked in Figure 5.
4. The third-order NLO coefficient of reported compouns should be given since they are all highlighted to be NLO crystals.
5. At the begaining of the introduction, the author highlighted the importance of nonlinear optical crystals, in the part, related papers are suggested to cite to support this statement, like 10.1038/s41566-023-01228-7; 10.1021/jacs.3c09573, 10.1002/anie.202316194.
6. The main mannscript has a lot of figures, some of which should be relocated to SI because they are not essential to the main text.
7. The experimental data for the determination of refractive index should be given since this is key property for NLO crytals.
8. The roles of different components in reported compounds on NLO property should be carefully analyzed using theoretical approaches.
9. Necessary discussion about the orign of the additional absorption peaks in Figure 4 is suggested to give.
