Tin　oxide　is　a　unique　material　of　widespread　technological.　applications,　particularly　in　the　field　of　strategic　functional　materials,　Versatile　strategies　for　growth　of　tin　dioxide　nanocrystals　are　of　fundamental　importance　in　the　development　of　micro/nanodevices.　After　an　extensive　search　of　the　published　literature,　it　is　found　that　previous　nanocrystals　were　assembled　either　by　aqueous　synthesis,　hydrothermal,　and　pyrolysis　or　by　epitaxial　approaches　through　the　gas　phase.　Herein,　tin　dioxide　nanocrystals　prepared　by　sol-gel　method　are　successfully　radiated　by　an　electron　accelerator.　The　microstructure　evolution　of　tin　dioxide　nanocrystals　is　evaluated　by　X-ray　diffraction,　high-resolution　transmission　electron　microscopy,　Raman,　thermogravimetric-differential　scanning　calorimetry,　and　automated　surface　area　analysis.　It　is　surprisingly　found　that　the　crystallinity　of　the　irradiated　tin　dioxide　powders　is　better　than　the　unirradiated　one.　The　clear　lattice　fringes　of　quantum　dots　are　investigated　in　detail　using　high-resolution　transmission　electron　microscopy.　The　sizes　of　tin　dioxide　quantum　dots　are　localized　in　the　range　of　2-4　nm.　Brunauer-Emmett-Teller　surface　area　analysis　indicates　that　the　specific　surface　area　of　the　irradiated　sample　is　much　higher,　which　is　almost　doubled　at　1400　kGy　with　an　irradiation　rate　of　8　mA/s　and　irradiation　time　of　50　s.　Raman　experiments　show　two　new　peaks　at　538　and　680　cm(-1).
