“…[6] Since various doping agents like amino acids, organic and inorganic compounds, rare earth have been introduced as doping in TGS crystals. Different metal ion dopants like Mn 2+ , [7] Co 2+ , [8] thiourea, [3] phosphoric acid, [9] potassium bromide, [10] Ni 2+ , [11] etc., are added to modify the optical properties of TGS crystals. [12] In this present work, investigation on the growth and characterization of yttrium-ion-doped TGS crystals (YTGS) have been carried out and the effect of dopant on the growth, structural, morphology, thermal, and dielectric have been investigated.…”
