Which is the definition of luminescence?
The emission of light a longer timescale, so that emission continues after excitation ceases.
The emission of light by a substance that has not been heated
Emission of light that is caused by the absorption of radiation at one wavelength followed by nearly immediate reradiation usually at a different wavelength and that ceases almost at once when the incident radiation stops
The emission of light during a chemical reaction which does not produce significant quantities of heat
Which is the definition of fluorescence?
The emission of light a longer timescale, so that emission continues after excitation ceases.
The emission of light by a substance that has not been heated
Emission of light that is caused by the absorption of radiation at one wavelength followed by nearly immediate reradiation usually at a different wavelength and that ceases almost at once when the incident radiation stops
The emission of light during a chemical reaction which does not produce significant quantities of heat
Which is the definition of phosphorescence?
The emission of light a longer timescale, so that emission continues after excitation ceases.

What is the difference between photoluminescence and chemiluminescence
Only photoluminesence involves the emission (release) of light
Only chemiluminescence involves the absorption of a photon
Only photoluminescence involves the absorption of a photon
Only chemiluminescence requires the addition of heat in order to produce a glowing effect
In the case of photoluminescence and chemiluminescence, what must be released for electrons to lose energy?
A photon
An electron
An proton
A neutron
Identify the following example as fluorescence, phosphorescence, or chemiluminescence (Jelly Fish)
Fluoresncence
Chemiluminescence
Phosphorescence
