Are the luminescant properties subclass of radiation emissivity?

[alanruttenberg]

Definitions

radiation emissivity: An Electromagnetic Radiation Property that inheres in a bearer in virtue of the capacity of that bearer to emit electromagnetic radiation of a given frequency.

luminescent property: An Optical Property that inheres in a bearer in virtue of that bearer's capacity to emit visible light, but which isn't the result of the bearer being heated.

I see emissivity mentions a given frequency, but https://en.wikipedia.org/wiki/Emissivity doesn't name that criteria as primary

Along these lines, would a better name for Opacity, be "Radiation Transmittance"?
It parallels the naming of its siblings, and reduces the confusion of having both "opacity" and "opaque" as terms.
A measurement of opacity is a measurement of transmittance.

There's also the issue that these seem to be parameterized by a frequency but we don't know how to relate that frequency to these terms. In any case, most of these transmit over a distribution of frequencies by varying amounts.

Take an example of a red filter. Does it have many many (well, infinite) translucency qualities, each at a different frequency? Or does it have one translucency quality which is a complex quality in that there is different transmittance for different frequencies. I would lean towards the latter.

As an aside, to try to avoid dealing with particle field duality, is it a viable strategy to stick to photons and aggregates of them? then frequency and wavelength are just other ways (or proxies for) measuring energy of a photon.
