摘      要：Whispering gallery mode(WGM)-enhanced nonlinear optical phenomena from crown-like nanostructure zinc oxide(ZnO)samples are *** samples are synthesized by vapor-phase transport *** morphology and crystal structure are examined and characterized by scanning electron microscopy(SEM),X-ray diffraction(XRD)and high-resolution transmission electron microscopy(HRTEM),and they are excited by femtosecond laser pulses with central wavelengths of 355 nm,800 nm and 1150 nm,*** typical stimulated emission presents a red shift compared with spontaneous emission,which is observed under the excitation of 355 nm with a relatively low *** ultraviolet(UV)frequency up-conversion emission is obtained when the excitation pulse wavelengths are selected as 800nm and 1150 nm,*** peak position and the relationship between the emission intensity and excitation intensity demonstrate that the UV up-conversion photoluminescence(PL)is induced by two-and three-photon *** PL characteristics and their WGM-enhanced mechanism are investigated.
