1. An apparatus for generating a three-dimensional image, the apparatus comprising:
a medium comprising an acid-sensitive photoinitiator, a photoacid, monomers, donors, and acceptors, wherein the acceptor has a non-fluorescent state and a fluorescent state, wherein at one wavelength of optical excitation an optical molecular switch molecule has a first state, and at a second state the optical molecular switch molecule fluoresces at a second wavelength of excitation; and
at least a first light source and a second light source into the medium, wherein light emitted by the at least first and second light sources are directed to contact the acid-sensitive photoinitiator, wherein a first wavelength activates the photo acid, and the second wavelength triggers polymerization of the monomers.
