  title = {Molybdenum blues with tunable light absorption synthesized by femtosecond laser irradiation of molybdenum trioxide in water/ethanol mixtures},
  abstract = {<p>Molybdenum blues (MBs) have attracted increasing attention due to their tunable structures and properties, which make them applicable in numerous fields. In this work, a novel strategy to synthesize MB nanorings by irradiating MoO<sub>3</sub>&nbsp;suspended in water/ethanol mixtures with intense femtosecond laser pulses is demonstrated. It is found that the MoO<sub>3</sub>&nbsp;can be dissolved in the water during laser irradiation to form molybdic acid, which provides an acidic environment for the formation of MB. Concentrations of ethanol as low as 1% result in the formation of MB and by adjusting the concentration of ethanol in the solvent, the absorption band can be tuned due to the modification of Mo<sup>V</sup>OMo<sup>VI</sup>&nbsp;entities. The MB synthesized in 30% ethanol appears the darkest blue and assembly of vesicles 115&nbsp;nm in size is observed. At high concentrations of ethanol (&gt;70%), H<em><sub>X</sub></em>MoO<sub>3</sub>&nbsp;and MoO<sub>3-</sub><em><sub>X</sub></em>&nbsp;are preferentially formed instead of MB. The photothermal conversion efficiency of the MBs synthesized in 1% and 30% ethanol is above 40%.</p>
