Rutile phase of SnO2 quantum dots of average size of 2.5nm were synthesized at a growth temperature of 70°C and characterized with XRD, TEM, FTIR and Raman analysis. The effective strain within the lattice of SnO2 quantum dots was calculated by Williamson–Hall method. The broad peaks in XRD as well as Raman spectra and the presence of Raman bands at 569 and 432cm−1 are due to lower crystallinity of...
