Excited state optical nonlinearity of inorganic metal cluster WSe4 (AgPPh3)3 Cl with picosecond pulses
Chemical Physics Letters 338 (2001) 108-112，-0001，（）：
The excited state absorption and refraction of a novel cubane-like shaped metal cluster WSe4 (AgPPh3). Cl in DMF solution were studied by using the Z-scan technique with laser pulses of 40 ps pulse-width at the wavelength of 532nm. The compound possesses a self-focusing performance. The positive nonlinear refraction is attributed to population transitions among singlet states. The cluster displayed a strong excited state absorption, which induced as ymmetry in the Z-scan results.
