“…Specifically, the optical thickness that leads to minimum reflectance and minimum reflectance change are completely different in each wavelength region. 7,9 From this simulation, we found that Ag with the overcoating of one pair of low refractive index layer and high refractive index layer consisting of Ag/ SiO 2 ͑54 nm͒ / TiO 2 ͑55 nm͒ would reach the maximum R vis of 99.3%, and we decided to apply it and make that multilayer high reflectance coating by sputtering.

A multilayer high reflectance coating consisting of Ag, SiO 2 , and TiO 2 with R vis of 99.3% was successfully designed by simulation based on Maxwell's equations. The authors found that providing the low refractive index SiO 2 layer with non-quarter-wave thickness ͑0.14 of nd / for 550 nm light͒ near the Ag layer made a leading contribution to this high reflectance. They successfully made a multilayer high reflectance coating of Ag/ SiO 2 / TiO 2 on polyethylene telephthalate film with R vis of 99.4% based on that simulation. A backlight unit with a coating of Ag/ SiO 2 / TiO 2 exhibited high luminance 1.04 times that of Ag alone. Ag atoms are mixed with Si atoms upon deposit of a SiO 2 layer on Ag in an atmosphere with O 2 . A SiO 2 -P layer deposited under O 2 free conditions from a SiO 2 ceramic target and a TiO x layer deposited from Ti work well for protection of the Ag layer from oxidation upon deposit of SiO 2 .
