摘要：
Disclosed is a multilayer structure wherein a first layer of a first material having an outer surface and a refracted index between 2 and 4 extends across an outer surface of a second layer having a refractive index between 1 and 3. The multilayer stack has a reflective band of less than 200 nanometers when viewed from angles between 0° and 80° and can be used to reflect a narrow range of electromagnetic radiation in the ultraviolet, visible and infrared spectrum ranges. In some instances, the reflection band of the multilayer structure is less than 100 nanometers. In addition, the multilayer structure can have a quantity defined as a range to mid-range ratio percentage of less than 2%.
