• SnHPO3 nanosheets were obtained by a facile exfoliation method.
• SnHPO3 nanosheets exhibit blue-shift in UV absorbance.
• The piezoelectric coefficients of SnHPO3 monolayer were calculated.
• The piezoelectric coefficients of SnHPO3 monolayer are larger than h-BN monolayer.
Tin phosphite nanosheets were synthesized by a facile exfoliation method. SnHPO3 nanosheets with a thickness of ∼2.6 nm readily form a stable colloidal suspension in ethanol using ultrasonic method. Structures and optical properties of the obtained nanosheets were investigated. The prepared SnHPO3 nanosheets exhibit an obvious blue-shift in UV absorbance compared with bulk SnHPO3 crystal materials. Moreover, the piezoelectric coefficients of SnHPO3 monolayer were calculated based on density functional theory, which are larger than that of h-BN monolayer, indicating this material could be a good candidate for designing electro-optical nano-devices.
