Nope. but I did ask you for a graph of CO2 v Temp you found acceptable. I guess you can't find one.

BTW - how did you determine it was CO2 in your greenhouse causing the heating? Sensors both inside and outside?

We KNOW a lot of the absorbed/emitted IR goes down because it is missing from the IR spectrum measured in satellites.

Just commonsense Lees. A molecule of CO2 vibrating somewhere in the atmosphere absorbs a photon and re-emits it nano or microseconds later. What is the orientation of the molecule? Random.

Get some commonsense Lees.

Wow. Can you describe the mechanism? The only thing I can find about converting visible light to IR is a suggestion to paint something black.

Not optimal for a greenhouse.

But what you seem to be saying is more IR causes more heat.

Although there seems to be this -

"We show that Ce3+ can be an efficient sensitizer for Yb3+ in the host lattice of yttrium aluminum garnet (YAG). With blue-light excitation to induce the 4𝑓→5𝑑 transition of Ce3+, characteristic near-IR emission of Yb3+ due to transition of 𝐹5⁄22→𝐹7⁄22 peaking at 1030 nm is generated as a result of energy transfer from Ce3+ to Yb3+. The result of spectral evolution with temperature indicates that the efficiency of energy transfer is enhanced owing to thermal effect. This evidence implies that the phonon-assisted process participates in the downconversion of YAG: Ce3+, Yb3+."

Conversion to NEAR infrared.

Very hightech. Also plenty of papers converting IR to visible light - also hightech.

You didn't say you had a hightech greenhouse.

Citation needed.

It is generally agreed that visible light can be refracted where some may be changed to IR.

If the light is reflected it will not enter the greenhouse.

Some light is reflected when hitting the glass but most passes through.

Energy is lost in both fractions. Energy cannot be created or destroyed.

Very good. Now describe the  refractive index of your glass that will give you some level of IR. The angle at which the sun strikes the glass, etc.

Energy may be transformed eg light to heat. It is not necessarily IR.
