Optical constants of sputtered ZrN films for heat mirror application
- Uppsala Univ. (Sweden). Dept. of Technology
Opaque and semi-transmitting film of ZrN have been reactively magnetron sputtered and their optical performance for solar control coating applications evaluated. The optical constants of the opaque films were determined from near normal reflectance measurements and Kramers-Kronig calculations over the interval 0.23--3.0 {micro}m. The thin film optical constants were determined with combined R- and T-measurements. Systematic variations with growth conditions were observed. Thin films were observed to high higher n-values in the visible, a change that could be partly compensated by substrate heating. For the triple layers: glass/ZrO{sub 2}/ZrN/ZrO{sub 2} it was noted that the crystallinity of the first oxide did not influence the refractive index of this oxide, but improved significantly the selectivity of the nitride growing upon it. Triple layers for solar control applications with 57% luminous transmittance and close to 1/3 each of solar transmittance, reflectance and absorption have been realized.
