当我使用export excel laravel时，应用程序没有继续？

This is my code, $infoNotificacion[1] is a excel but i need export and continues:

$all=array("changes"=>$changes,"noti"=>$noti,"infoNotification"=>$infoNotification[0]);
    $infoNotification[1]->export('xlsx');
    return view('sendEmail')->with('htmls',$all);

But the important line is the second because I need return the view but i don't know.

please help me.
