ABSTRACT
This study investigates the fluorescence emission profile of Thioxanthone in Ethanol due to two photon absorption
excitation. Thioxanthone was investigated as Photosensitizer to fabricate cell scaffold in Ethoxylated Bis Phenol A
Dimethacrylate for tissue repair in the field of biomedical. Also Incident Laser Power Effects were analyzed and
found that the Fluorescence Intensity increases with increasing Incident Laser Power, Io, and the emitted fluorescence
obeys the square-law dependences. Also when the Photo-Sensitizer was excited at different wavelengths (800nm,
400nm), it was found that Fluorescence Emission Profile did not change but variations occurred only in Fluorescence
Emission Intensity.
