While GaInAs quantum well (QW) emission wavelength is practically limited to approximately 1200 nm [6], by using dilute nitride GaInNAs QWs with a tiny fraction of nitrogen added to the highly strained GaInAs, the emission wavelength can be extended to 1220-1240 nm for high luminosity red light generation at 610 to 620 nm by frequency conversion [5].

A reminder shock (0.6 mA, 2 s) was given immediately after the mice were placed in white triangular chamber B (22 cm wide, 19 cm deep, 27 cm high) with red light and a stainless steel grid floor.
Net photosynthesis and stomatal conductance were measured in attached leaves of Malva parviflora L. as a function of photon irradiance at 457.9 and 640.0 nanometers.Photosynthetic rates and quantum yields of photosynthesis were higher under red light than under blue, on an absorbed or incident basis.Stomatal conductance was higher under blue than under red light at all intensities.
Hanifin, J. P. et al. High-intensity red light suppresses melatonin.
The number of induced microrhizomes was highest under red light (60%) and lowest under blue light (38%).
We detected significant calcium responses in aBN1, aBN2, and aDN1, but only a weak response in aDN2 even with high-intensity red light.
Activation of aBN1 induced a calcium response in aBN2, whereas only high-intensity red light activation of aBN2 could cause a weak calcium response in aBN1.
As the reviewers pointed out, we now indicate that only high-intensity red light activation of aBN2 could cause a weak calcium response in aBN1.
Our results, we believe, indicate that besides the triplet energy, charge balance is a crucial determinant to develop high efficiency red light-emitting electrophosphorescent polymers.
