Growth and characterization of l-histidine cadmium chloride monohydrate a semiorganic nonlinear optical crystals

Growth and characterization of hexamethylenetetramine crystals grown from solution

“…4 it can be observed that dieletric constant is very high at low frequency then decreases slowly and attains a constant value at higher frequencies. Very high dielectric constant at low frequency may be due to the presence of all four polarization modes, namely electronic, ionic, orientational and space charge polarization [14]. At a very high frequency vibration may occur, which causes that the dipoles are not able to follow the alternating field and the dielectric constant decreases with an increase in frequency, attaining a constant value [15].…”

Synthesis, growth and characterization of l-asparagine cadmium bromide: A novel semiorganic nonlinear optical single crystal

“…The broad absorption peak at 3379 cm −1 was due to NH 2 asymmetric stretching vibration [15]. The peaks obtained at 2526 and 2148 cm −1 were due to NH 3 + symmetric stretching vibration [16]. The C H stretching vibration was identified from the peak around 2000 cm −1 [17].…”

“…The peak around 890 cm −1 was due to C C N symmetric vibration [18]. The stretching vibration of C C indicated the peak at 836 and 804 cm −1 [16]. The COO − bending vibration also occurred around 669 cm −1 .…”

Synthesis and Characterization of Cerium Doped Urea Thiourea Naphthylamine Single Crystal Developed by Slow Evaporation Method

“…Growth of single crystals and their characterization towards device fabrication have assumed great impetus due to their importance for both academic as well as applied research. To enable a material to be potentially useful for NLO applications, the material should be available in bulk single crystal form 9 . So, crystal growth of new nonlinear optical materials and investigation into their properties has become most indispensable and efficacious disciplines in the field of materials science and engineering.…”
