“…Recently, nonlinear optical (NLO) materials have been found to have important applications in, for example, opto-electronic, photonic, data conversion, retrieval, storage and frequency-doubling devices (Saleh & Teich, 1991;Penn et al, 1991;Shakir et al, 2009;Shakir, Kushwaha et al, 2010;Shkir, Abbas et al, 2014;Badan et al, 1993;Zaitseva & Carman, 2001;. Luminescent dyed crystals exhibit better properties than polymers and glasses as they possess superior thermal conductivity, low dispersion and intrinsic polarization, have fewer defects, and can be used in laser devices (Yang & Ozin, 2000, Wanke et al, 1997.…”
