Phosphorescence Studies of Reverse Saturable Absorption Materials

MRS Proceedings, 1999
AbstractPhosphorescence studies of reverse saturable absorption materials (RSA) are discussed. Absorption and emission measurements of an RSA material, specifically Zinc 2,3,7,8,12,13,17,18-octabromo-5,10,15,20-tetraphenylporphyrin (ZnOBP), are performed in a proprietary host polymer.

Saturable and reverse saturable absorption of a linear polymer in dimethylformamide

Applied Physics B: Lasers and Optics, 2007
Nonlinear absorption properties of a linear polymer (P1) in dimethylformamide (DMF) have been investigated using an open aperture Z-scan technique with 8 ns laser pulses at 532 nm. It was found that P1 shows saturable absorption (SA) at low intensities and a transition from SA to reverse saturable absorption (RSA) with an increase in intensities.

Nonlinear optical effects related to saturable and reverse saturable absorption by subphthalocyanines at 532 nm

Chemical Communications, 2005
It is found that both effects of saturable absorption and reverse saturable absorption are obtained with a solution of subphthalocyanine at 532 nm depending on the intensity of 9 ns laser pulses; saturable absorption occurs at lower intensity levels whereas the reverse effect prevails at higher levels; contrary to expectations, subphthalocyanines can ...

The saturable absorption and reverse saturable absorption properties of Cu doped zinc oxide thin films

Chemical Physics Letters, 2017
Abstract We present the structure and nonlinear absorption (NLA) properties of Cu-doped ZnO (CZO) films prepared by magnetron sputtering. The films were characterized using X-ray diffraction (XRD) and scanning electron microscopy (SEM), respectively. The results show that the CZO films can maintain a wurtzite structure. Furthermore, the open-aperture
