Bi2WO6 nanosheets with different morphologies were synthesized by adjusting the ratios of CH3CH2OH to H2O using solvothermal method. Meanwhile, the effects of morphology on photoluminescence of Bi2WO6 nanosheets were explored. The crystalline, edges, and interlayer spacings of Bi2WO6 nanosheets were first enhanced and then reduced with the increase in proportion of CH3CH2OH in the solvent. When the ratio of CH3CH2OH to H2O was 1∶1, the values of edges, interlayer spacings and specific surface areas for the Bi2WO6 nanosheets were attained maximum, which contributed to the excellent photoluminescence. However, when the ratio was more than 1∶1, the values of edges, interlayer spacings and specific surface areas for Bi2WO6 nanosheets were reduced, which went against the improvement of photoluminescence. The results indicated that there was a synergistic effect of CH3CH2OH and H2O on the formation of morphology and the improvement of photoluminescence for Bi2WO6 nanosheets.
