A luminescent device is described, including: a fiber-shaped core including a first hydrogel including a first hydrogel polymer, wherein the fiber-shaped core has an elongated body and a side-wall surface along the elongated body; a luminescent layer including a first elastomeric polymer and a luminescent material, coaxially disposed with the fiber-shaped core, and surrounding the fiber-shaped core's side-wall surface; a hydrophilic layer including a second hydrogel comprising a second hydrogel polymer, coaxially disposed with the fiber-shaped core, and surrounding the luminescent layer; and an elastomeric layer including a second elastomeric polymer, coaxially disposed with the fiber-shaped core, and surrounding the hydrophilic layer. Methods of fabricating the luminescent device and using the luminescent device are also described. |
