Growth of multilayer thin film structures containing dielectric and metal layers using physical vapor deposition is investigated for use in applications requiring the control of thermal and solar radiation propagating through glass windows. In particular, metal-dielectric multilayer structures reflecting UV, near-infrared and thermal radiations whilst maintaining a maximum transmission in the visible range are prepared using both an E-Beam and Thermal evaporator and a RF Magnetron sputtering system. Measured transmittance spectra for the developed structures are in agreement with simulation results and demonstrate that with the use of optimum metal-dielectric layer combination it is possible to realize a coated glass transmitting most of the visible light through and reflecting most of the UV, solar and thermal infrared radiations.
