(A phototransistor can actually become more sensitive when prebiased with some ambient light, but that's another story.) 5. If ambient light is swamping the receiver, try using an optical filter that transmits the wavelength being used Increasing the operating temperature of a photodiode device results in two distinct changes in operating characteristics. The first change is a shift in the Quantum Efficiency (Q.E.) due to changes in the radiation absorbtion of the device. Q.E. values shift lower in the UV region and higher in the IR region.
