Interior energy-activation of photo-reactive species inside a medium or body

A method for curing of a radiation-curable medium, comprising:

• applying an initiation energy throughout a composition comprising 1) an uncured radiation-curable medium and 2) at least one energy modulation agent, wherein the initiation energy interacts with the energy modulation agent to directly or indirectly cure the uncured medium by polymerization of polymers in the medium;
• and
• curing the radiation-curable medium by activating a photoinitiator in the radiation-curable medium,
• wherein said energy modulation agent has a normal predominant emission of radiation in a first wavelength range (WR1) outside of a second wavelength range (WR2) known to activate the photoinitiator, but under exposure to said applied initiation energy cures the medium.

A system for producing a change in a medium disposed in an artificial container, comprising:

• a mechanism configured to provide to the medium 1) an activatable agent and 2) at least one energy modulation agent, said energy modulation agent is configured to emit light into the medium upon interaction with an initiation energy;
• and
• an initiation energy source configured to apply the initiation energy to the medium,
• wherein said energy modulation agent has a normal predominant emission of radiation in a first wavelength range (WR1) outside of a second wavelength range (WR2) known to produce said change, but under exposure to said applied initiation energy produces said change.

A system for curing of a radiation-curable medium, comprising:

• a mechanism configured to supply an uncured radiation-curable medium including an activatable agent and at least one energy modulation agent into the uncured radiation-curable medium;
• and
• an initiation energy source configured to apply an initiation energy throughout a region including the uncured radiation-curable medium,
• wherein said energy modulation agent has a normal predominant emission of radiation in a first wavelength range (WR1) outside of a second wavelength range (WR2) known to produce said change, but under exposure to said applied initiation energy produces said change.

A radiation-curable article, comprising:

• a radiation-curable medium;
• and
• at least one energy modulation agent distributed throughout the medium;
• said energy modulation agent being a substance which is capable of converting initiation energy to a light capable of curing the radiation-curable medium by polymerization of polymers in the radiation-curable medium,
• wherein said energy modulation agent has a normal predominant emission of radiation in a first wavelength range (WR1) outside of a second wavelength range (WR2) known to produce cure the radiation-curable medium, but under exposure to said applied initiation energy cures the radiation-curable medium.

A method for producing a patterned element inside a structure, comprising:

• (1) placing inside the structure a radiation curable medium including at least one energy modulation agent, said energy modulation agent is configured to emit light into the medium upon interaction with an initiation energy;
• and
• (2) applying to the medium said initiation energy from a directed or focused energy source,
• wherein said energy modulation agent has a normal predominant emission of radiation in a first wavelength range (WR1) outside of a second wavelength range (WR2) known to radiation curable medium, but under exposure to said applied initiation energy cures the radiation curable medium and produces the patterned element inside the structure.
