Single crystalline tetragonal rutile SnO2 nanorods with curved beak-like tips of various lengths were synthesized using Au as a catalyst by thermal evaporation with different precursor flow rates. The cathodoluminescence (CL) spectrum shows that the long beak-like SnO2 nanorods exhibit stronger orange emission at 600 nm, while the short beak-like SnO2 nanorods exhibit stronger blue emission at 480 nm. The morphology and optical properties can be modified by altering the oxygen content. [DOI: 10.1143/JJAP.47.8141]
