Linear light down-conversion LDC has been a convenient method for generating light by applying a short wavelength photon to a medium that responds by emitting one, two, or more longer wavelength photons. Such LDC processes like photoluminescence in s

In this report, we show both theoretically and experimentally how the IR signature of a semiconductor scene (with band gap energy Eg) can be monitored through contactless emissivity control even if this scene thermometric temperature is kept constant

In contrast to radiative cooling by light up conversion caused exclusively by a low-entropy laser pump and employing thermally assisted fluorescence/luminescence as a power out, we demonstrate light down conversion cooling by incoherent pumps, 0.47

A Si-based fast (frame rate >1 kHz), large-scale (scene area 100 cm2), broadband (3–12 μm), dynamic contactless infrared (IR) scene projector is demonstrated. An IR movie appears on a scene because of the conversion of a visible scenario projected

To bypass indirect bandstructure limitations in Ge and have it effectively emitting, we employ light down conversion process at elevated temperatures (emissivity enhancement technique). By applying short wavelength pump light (λin, interband electro
