I check the UV of upper layer that give me two peaks at 240nm and 280nm. Then i checked PL that give me peaks at 333nm. it is useful ?
is it Manganese QD in organic layer?
i was doing experiment, by using KMnO4, in water and organic solvent by using a surfactant then put acid and give this material hydrothermal treatment. At the end i get two layers, one upper golden layer and second colorless layer.
what is this please guide me. i will be very thankful to you.
normally, KMnO4 could be reduced to MnO2 or Mn3O4 etc. none of them showed to be golden layer, so first you can conduct XPS or XRD to confirm the composition of your particle. and Mn could be used for MR imaging or photothermal therapy, and some of them were reported to have enzyme activity. i hope this could help you.
Tao Yang may i get ur wechat sir please, because im really getting my samples in liqiut. im very shocked even 5 grams solid KMnO4 totally dissolved in 45ml n hexans
