The present disclosure generally relates to passivated photonic crystals, for example, for thermophotovoltaic power generation or other applications. Certain aspects are generally directed to photonic crystals comprising tantalum and/or other refractory metals passivated with a coating. In some cases, the passivating coating may comprise a ceramic material, for example, zirconia and/or hafnia. The passivating coating may prevent or reduce the exposure of the underlying tantalum and/or other refractory metals to coming into contact with water vapor. In some cases, the passivating layer separates a surrounding gas from coming into contact with the photonic crystal. Other aspects are generally related to methods of making or using passivated photonic crystals, kits including such passivated photonic crystals, or the like.
An article, comprising:
The article of claim 7, further comprising a thermophotovoltaic cell in the exterior region and positioned to receive radiation emitted from the photonic crystal. The article of any one of claims 1-8, wherein a vapor pressure of the coating is less than or equal to 10−5 kPa.
An article, comprising:
The article of any one of claims 13-18, further comprising an inner substrate in physical contact with the photonic crystal. The article of any one of claims 13-19, wherein the photonic crystal positioned to emit radiation through the coating and the interior region.
A method, comprising:
The method of any one of 26-29, wherein the zirconia, hafnia, or alumina are present as a coating on at least a portion of the photonic crystal.
A method, comprising:
