英文摘要	Two-photon excited fluorescence (tpef) under continuous-wave excitation from silicon particles produced by a pulsed laser is investigated. spectra and images of tpef from silicon particles are studied under different excitation intensities and operation modes (continuous wave or pulse). it is found that the photoluminescence depends superlinearly on the excitation intensity and that the spectral shape and peaks vary with different silicon particles. the above phenomena show the nonlinear behavior of tpef from silicon particles, and stimulated emission is a possible process.
