You still haven't said what exactly you are looking for. I suspect you want to see more details in the dark areas but retain a vibrant sunset? In that case, meter for the sunset, note the shutter speed and aperture, change to manual using those settings, shoot several times increasing one of the settings by one stop each time (ie increase exposure).
Alternatively, go into the camera menu system (or a dial may be available on the camera)and select increase exposure compensation. Most menus may only allow you up to + 2 stops, which may not be sufficient to get the exposure you require.
Yet another alternative is to use the HDR technique, which is whole topic by itself.
Good luck.

Thanks for your opinion, Chinaman. It is always welcome, but the topic is Shooting Silhouettes. Sunsets were mentioned but only passing. Sorry, mate, good information but wrong topic.
