“…Several key properties such as morphology, growth rate, crystalline perfection, optical transparency, band gap, second harmonic generation (SHG) efficiency, laser damage threshold (LDT) are found to be enhanced/change due to some additives or dopants in ZTS as well as many other crystals [9,[20][21][22][23][24][25]. Single crystal growth with dye doping has been attracted to many researchers and scientist due to their possible applications in solid state lasers as well as many other applications [26][27][28][29][30][31][32][33][34][35][36][37][38]. Recently Benedict et al, has studied the dyeing processes in crystals and designed simple sulfate, phosphate and carboxylate salts single crystals and grown in solution [39].…”

In present work, the pure and brilliant green dye doped single crystals of nonlinear optical zinc tris(thiourea) sulfate have been grown for the first time using slow evaporation solution technique from their aqueous solutions. The powder X-ray diffraction and FT-Raman spectroscopic investigations were carried out to confirm and identify the crystal structure and vibrational modes, respectively. The strong effect of dye on crystals morphology is observed. For optical band gap analysis the diffused reflectance was measured. Two absorption bands were observed in the diffused reflectance spectrum centered at *425 and 627 nm due to brilliant green dye. Room temperature PL study with 310 nm excitation show noticeable enhancement in UV-blue emission band centered at 348 nm due to dye doping and also the enhancement in violet-blue emission centered at 420 nm was observed. Mechanical strength was also found to be enhanced with doping. All the results show that the properties of ZTS crystals are enriched due to dye doping and can be applied in optoelectronic devices.

Single crystals of 0.01 and 0.02 mol% crystal-violet dye doped triglycine sulfate (NH 2 CH 2 COOH) 3 H 2 SO 4 (TGS) have been grown by slow evaporation technique. Enhanced dielectric, optical, thermal and mechanical behavior has been achieved by dye doping. Monoclinic structures showing particular coloring pattern and morphology change with dye concentration were obtained. Various functional groups and dye incorporation in grown crystals were confirmed qualitatively by FTIR and Raman analysis. A significant increase in Curie temperature from 50 to 55 °C with decrease in maximum permittivity has been observed. UV-Vis spectra showed an increased transmittance window and increased optical band gap from 5.61 to 6.11 eV as a result of doping. Increase in the sharpness and intensity of photoluminescence peak with a blue shift have been observed in doped crystals. The thermal stability and the decomposition temperature were found to increase by about 10 °C in 0.01mol% dye doped TGS. The mechanical strength of the grown crystals was estimated by Vickers microhardness test and was found high for dye doped TGS. High piezoelectric charge coefficient d 33 of 16 pC/N was observed for pure TGS which decreased as a result of dye-effect. The fabrication of patch antenna was carried out after simulating its resonant frequency that makes it suitable for telecommunication applications.

“…[24] In the last few decades, organic-dye-doped single crystals have been grown for their applications in optoelectronics and solid state lasers. [20,[25][26][27][28][29][30][31][32][33][34][35][36] Such applications necessitate the development of dyed single crystals of organic, inorganic, and semi-organic materials. Hitherto, reports on amaranth, titan yellow, and brilliant green dye-doped/-added ZTS crystals have been scarce.…”

In this work, uranine-dyed zinc (tris) thiourea sulfate (ZTS) monocrystals, 26 mm×15 mm×10 mm in size, were synthesized by the solution method at ambient temperature. Their purity, crystallinity, lattice parameters, and functional modes were studied by x-ray diffraction, Fourier transform-infrared spectroscopy (FT-IR), and FT-Raman spectroscopy analyses. The sodium ion content of the crystals from the dye was confirmed by elemental analysis. The diffused reflectance spectral analysis of the dyed crystal revealed a characteristic absorption band at 490 nm attributed to the presence of the dye. The calculated band gaps of the non-dyed and dyed crystals were 4.53 and 4.57 eV, respectively. A green emission peak at ∼ (512 ± 4) nm was observed in the photoluminescence spectrum of the uranine-dyed crystals. A differential scanning calorimetry study confirmed that the thermal stability improved owing to the addition of the dye. Dielectric and microhardness studies were conducted to examine the significant improvements in the corresponding properties of dyed crystals. The results demonstrated the competency of the dyed ZTS crystals for applications in optoelectronic devices.
