Abstract: A hybrid structure ultraviolet dye for leak detection in an appliance includes a ceramic matrix defining pores, and fluorophores encapsulated in nanoparticles bonded to the ceramic matrix within the pores. Upon excitation, the fluorophores release energy and emit fluorescent light to be detected under an ultraviolet lamp. The hybrid structure ultraviolet dye can be included in the refrigerant of a sealed system such that upon refrigerant, the hybrid structure ultraviolet dye, or both exit the sealed system at a leak onto external surfaces of the components, the color emitted by the fluorophores can be detected via application of a UV light.
