Crystal growth and optical properties of 4-aminobenzophenone crystals for NLO applications

Studies on bulk growth, structural and microstructural characterization of 4-aminobenzophenone single crystal grown from vertical Bridgman technique

“…3.3c Acetone as etchant: Since 4-ABP is highly soluble in acetone (Lal et al 1997), etching with acetone resulted in complete dissolution of the crystal and no etch pits were observed. The dissolution patterns are shown in figure 6c and d. For the etching time of 10 s, the existence of steps (figure 6c) on the crystal surfaces enables the detection of the point of emergence of screw dislocation.…”

“…This is due to that 4-ABP is readily photolysed in solution and changed to radical species which are themselves very reactive. However, reports are available on the growth and studies of 4-ABP single crystals from solution and melt growth techniques (Pan et al 1993(Pan et al , 1997Lal et al 1997;Li et al 1997a, b;Anandha Babu et al 2009). The reports (Lal et al 1997;Anandha Babu et al 2009) concluded that the melt grown 4-ABP crystals are poor in quality and also small in size.…”

Effect of solvents on the bulk growth of 4-aminobenzophenone single crystals: A potential material for blue and green lasers

“…Organic NLO crystals are superior to inorganic materials because of their high NLO efficiency and fast response than the inorganic NLO materials [1,2]. Benzophenone and its derivatives are promising organic NLO material with good optical and mechanical properties [3][4][5][6][7][8][9][10]. The derivatives of benzophenone have large NLO susceptibilities and short cut-off wavelengths up to deep UV region (<400 nm) [8][9][10].…”

The derivatives of benzophenone have large NLO susceptibilities and short cut-off wavelengths up to deep UV region (<400 nm) [8][9][10]. Among the derivatives, 4-aminobenzophenone (4-ABP) is one of the best derivatives of benzophenone with the SHG efficiency of 360 times that of Ammonium dihydrogen Phosphate (ADP) [6,7].…”

Single crystal growth of 4-aminobenzophenone using nanoresolution translation by the Bridgman technique and its characterization

“…A 4ABP single crystal was grown from Kyropoulos method by Pan et al [9] and Bridgman-Stockbarger method by Lal [10]. For Bridgman-Stockbarger method the temperature gradient was 8-10 1C/cm.…”
