Edmund  Scientific - Industrial Optics Division, 1997 Optics and Instruments Catalog :

Sells an infrared detector screen, manufactured by Kodak(TM) emitting visible light photons, when irradiated with infrared photons. Screen's phosphor emits orange light (0.55 μm to 0.7 μm) from infrared photons.

Infrared photons add up to Orange photons.

This chart by Edmund Industrial Optics (R) displays the visible light's shorter wavelengths and higher frequencies, emitted after stimulation from near-infrared photons longer wavelengths and lower frequencies. 

Stimulation Range     Band 1: from 790nm to 840nm    Band 2: from 870nm to 1070nm      Band 3: 1550nm

Emission Color          Green (550nm), other peaks at Red (673nm) and Blue (400nm)

 

Near-Infrared photons add up to visible photons.
