Inspired by the naturally occurring fluorescent mineral, ferroan sphalerite, [(Fe,Zn)S] nanoparticles were synthesized by a three component reaction of [Fe(Mes)2]2 (Mes = mesityl or C6H2Me3-2,4,6), [Zn(Et)(ONep)(py)]2, and elemental S via both solution and solvothermal routes. The resultant nanoparticles are ≤3 nm and absorb at λmax = 281 nm emitting a bright blue color (λem ∼400 nm).

- 21.General Synthesis of (FeZn)S Nanoparticles. Two routes were explored to synthesize the ferroan sphalerite nanoparticles. All compounds described below were handled with rigorous exclusion of air and water using standard Schlenk line and glove box techniques. Octadecene and toluene were stored under argon and used as received (Aldrich) in SureSeal™ bottles. (A) The first route used a mixture of [Fe(Mes)2]2 (0.022 g, 0.037 mmol) and [Zn(Et)(ONep)(py)]2 (0.25 g, 0.69 mmol) dissolved in 25 mL of toluene. This solution is placed in three-neck round bottom equipped with a reflux condenser and a septum. Under flowing argon, the solution is brought to reflux conditions (∼200 °C) and 1 mL of a solution of S (0.023 g, 0.73 mmol) dissolved in octadecene was injected via syringe. A turbid dark brown solution formed immediately and the mixture stirred for 30 min at reflux conditions then was cooled to room temperature. After centrifugation, a yellow mother liquor and brown precipitate was collected. (B) The second route used a 48 mL Parr acid digestion bomb. In the glove box, 15 mL of toluene was added to [Fe(Mes)2]2, [Zn(Et)(ONep)(py)]2, and elemental sulfur in the Teflon vessel. The reaction was heated at 10 °C/min to 200 °C and held at this temperature for 48 h. After cooling, a turbid dark brown solution was collected and centrifuged. Again, a yellow mother liquor and brown precipitate was isolated. An aliquot of the particles dispersed in the mother liquor was placed directly onto a Carbon Type-B copper Transmission Electron Microscopy (TEM). TEM grid (300 mesh) purchased from Ted Pella, Inc. The aliquot was then allowed to dry overnight. The resultant particles were studied using a Philips CM 30 TEM operating at 300 kV accelerating voltageGoogle Scholar
