Copper(II) acetate, zinc(II) acetate, and tin(IV) acetate are weighed so that the total amount of metal ions is 2.0&#xd7;10mol and the molar ratio of ions is Cu:Zn:Sn=2:1:1, and 2.0 cmof oleylamine is added to prepare a mixed solution. Apart from this, 1.0 cmof oleylamine is added to 2.0&#xd7;10mol of sulfur powder to prepare a mixed solution. These mixed solutions are separately heated at 60&#xb0; C. and mixed at room temperature. The pressure in a test tube is reduced, followed by nitrogen filling. The test tube is heated at 240&#xb0; C. for 30 minutes and then allowed to stand until room temperature. The resultant product is separated into a supernatant and precipitates by centrifugal separation. The separated supernatant is filtered, methanol is added to produce precipitates. The precipitates are dissolved by adding chloroform to prepare a semiconductor nanoparticle solution.
