Growth and characterization of piperazinium 4-nitrophenolate monohydrate (PNP): A third order nonlinear optical material

Studies on Growth, Spectral, Thermal, Mechanical and Optical Properties of 4-Bromoanilinium 4-Methylbenzenesulfonate Crystal: A Third Order Nonlinear Optical Material

“…The Z-scan measurements revealed that 4BPTS exhibited good third-order non-linear optical properties such as non-linear refractive index and nonlinear absorption coefficient given in Table 1. The values obtained are in good agreement with the earlier reports of piperazinium 4-nitrophenolate monohydrate (PNP): A third order nonlinear optical material 15 . …”

Growth and characterization of a third order nonlinear optical single crystal: Ethylenediamine-4-nitrophenolate monohydrate

“…The CÀ ÀNO 2 stretching is observed as sharp Raman peak at 1166 cm À1 with corresponding IR band near 1157 cm À1 . This peak is reported at 1169 cm À1 in piperazinium 4-nitrophenolate monohydrate [16]. The phenyl ring CÀ ÀH out of plane deformation is assigned to peaks at 851 cm À1 and 806 cm À1 while the deformation type of the ring is assigned to the IR peak at 692 cm À1 .…”

“…In a recent communication, our group has also reported piperazinium 4-nitrophenolate monohydrate as a potential third order NLO material [16].…”

Growth and characterization of Piperazinium adipate: A third order NLO single crystal

“…Table 2 summarizes the experimental details and the results of the Z-Scan technique for PzA. The calculated values of nonlinear refractive index, nonlinear absorption coefficient and third order NLO susceptibility are found to be slightly high with respect to piperazinium meso tartrate [14], piperazinium 4-nitrophenolate monohydrate [15] and adipate crystals [18,19]. The hydrogen bond interactions between the piperazinium cations and the long adipate anions can be attributed to such high NLO responses.…”

“…Recently, piperazinium meso tartrate [14] and piperazinium 4-nitrophenolate monohydrate [15] are shown to be potentially good third order NLO materials. The presence of hydrogen bond interactions greatly influences the NLO activity in these materials.…”
