Slow output settling from OPA380 transimpedance

Other Parts Discussed in Thread: OPA380

Hi,

I have build a transimpedance amplifier using OPA380. When I switch on a UV LED (remains on) and directed it to the photodiode in the transimpedance, the amplifier's output rises to a certain level and then starts to decay slowly. Can anyone help to explain why the response behaves this way?  

The photodiode is from Opto Diode.

Thanks.
