Abstract
A vehicle emissions system is provided that includes a tail pipe configured to emit a first emission, a heat shield positioned proximate the tail pipe having a shield substrate. A semiconductor layer is positioned on the shield substrate and configured to convert the first emission into a second emission. An overmold is positioned over the semiconductor layer.
Claims17
A vehicle emissions system, comprising:
- a tail pipe configured to emit a first emission;
- a heat shield positioned proximate the tail pipe and having a shield substrate wherein ambient air extends between the heat shield and the tail pipe;
- and
- a semiconductor layer positioned between and in contact with a tie layer and an overmold, the tie layer in contact with the shield substrate, wherein the semiconductor layer is configured to convert the first emission into a second emission and a space is defined between the semiconductor layer and the tail pipe.

A vehicle, comprising:
- an emissions system comprising at least one of a tail pipe, a muffler and a catalytic converter, the emissions system configured to emit a first emission having a wavelength greater than about 800 nm;
- a heat shield spaced apart by ambient air from the emissions system;
- and
- a semiconductor layer comprising quantum dots coupled with the heat shield configured to absorb the first emission and emit a second emission.

A vehicle, comprising:
- a tail pipe configured to emit a first emission;
- a heat shield spaced apart from the tail pipe with ambient air in-between the heat shield and the tail pipe, wherein a gap is defined between the tail pipe and the heat shield;
- and
- a semiconductor layer in contact with the heat shield and configured to absorb the first emission and emit a second emission.
