TiO2 films with enhanced photosensitivity were deposited on alkali free glass substrates without intentional substrate heating by pulsed DC magnetron reactive sputtering with an average thickness of about 2μm. Three dyes, commercial N719 and two new organic dyes were impregnated in order to control the optical spectral selectivity of such ﬁlms. The type of dye used proved to dramatically inﬂuence the device's response to radiation pulses. The practical breakthrough is the use of different dyes according to the region of the electromagnetic spectrum one wants to detect. Devices with photocurrent 6 orders of magnitude higher than the dark current (from∼2×10-12 to 2×10-6 A for a 100 V bias) were fabricated with a spectral response within the visible range of the electromagnetic spectrum. In addition, this approach is likely to allow for the fabrication of hybrid photodetectors on cheap heat sensible ﬂexible polymeric substrates.
