Abstract
The present disclosure is a heat blocking device 101 that includes a heat blocking film 10 including: a particle that absorbs an infrared ray and generates an electron and a hole; and an acceptor that receives the electron or the hole from the particle. A charge carrier selected from the electron and the hole is released from the heat blocking film 10 to an outside of the device. The heat blocking device 101 can function as a “heat removing” device. The heat blocking film 10 may be a single-layer film or a multilayer film.
Claims8
A heat blocking device that blocks at least a part of an infrared ray with which the heat blocking device is irradiated, comprising
- a heat blocking film including:
- a particle that absorbs the infrared ray and generates an electron and a hole;
- and an acceptor that receives the electron or the hole from the particle, wherein
- at least a part of charge carriers selected from the electron and the hole are released from the heat blocking film to an outside of the heat blocking device, and
- the heat blocking film has a light transmittance of 24% or more at a wavelength of 700 nm.
A heat blocking device that blocks at least a part of an infrared ray with which the heat blocking device is irradiated, comprising
- a heat blocking film including:
- a particle that absorbs the infrared ray and generates an electron and a hole;
- and an acceptor that receives the electron or the hole from the particle, and
- a non-light-transmissive electrode, wherein
- at least a part of charge carriers selected from the electron and the hole are released from the heat blocking film to an outside of the heat blocking device, and
- a region in which the electrode is formed is less than 50% of a light receiving region from which the infrared ray enters the device.
A heat blocking device that blocks at least a part of an infrared ray with which the heat blocking device is irradiated, comprising
- a heat blocking film including:
