Hello everybody
I have synthesized metal oxide quantum dots by hydrothermal route in the presence of oleylamine and 1-octadecene. After the reaction, a creamy paste kind of material was obtained. I washed this with excess acetone and centrifuged, retrieved the precipitates followed by drying at 55 degree C overnight in vacuum oven. When i checked the XRD of the dried white powder I found many unknown peaks at theta value 15-20 degree with broad peaks of TiO2 anatase as well. I wonder these must be the organic impurities. Can someone guide me how to get rid of these organic impurities? Please find attached the XRD data.
PS: The paper i followed to synthesize these quantum dots have reported very decent XRD data but in my case it isn't. Its TiO2 quantum dots
Thank you all.
