AB - Nanofluids due to their good thermal conductivity and stability, have been  proposed as a way to surpass the performance of currently available heat  transfer fluids in the near future. In this work，we focuses on the  preparation of nanofluids with excellent stability and thermal conductivity,  which a new type of stable BiOIO3 (one type of infrared nonlinear optical  crystal) nanofluids is successfully prepared by using the two-step method.  After the initial physical characterization of BiOIO3 particles, five  different dispersants are used to disperse the BiOIO3 nanoparticles, and the  best performing nanofluids with a zeta potential value of 144.45 and an  average particle size of 22.90nm could be prepared with PVP dispersant.  Furthermore, the addition of PVP dispersant in UV-Visible experiments smooth  the light absorption curve of the nanofluids, reach a peak of 1.1 at around  350 nm. In the most important thermal conductivity test, the value of  thermal conductivity of BiOIO3 nanofluid becomes larger with increasing  concentration at 50°C, reaching a maximum value of 1.52 at 0.134vol%, which  increases by 0.72 over the same volume concentration of TiO2, indicating the  importance of the laminar structure. In view of the excellent properties,  new laminar structured nanofluids with light-absorbing properties are  expected to receive more attention and exploration in the future
