Optical constants (a) ε1 and (b) ε2 of Pt in graded index layer (t1, t2, t3, t4) and of Pt in constant index layer (t3 and t4), of NiCr in the NiCr sample, of Ti in the NiCr/Ti sample and of Pt (Bulk). Solid lines represent optical constants of nanocrystalline Pt in graded index Pt layer and dashed lines represent optical constants of nanocrystalline Pt in constant index Pt layer. Dark blue, light green, and light brown solid lines represent optical constants of NiCr in the NiCr sample, of Ti in the NiCr/Ti sample and of Pt (Bulk)15, respectively. MSE for fitted samples NiCr, NiCr/Ti, t1, t2, t3 and t4 are 0.078, 0.177, 0.676, 0.625, 0.772 and 0.801, respectively.
