PHPExcel integration into Zend Framework

My actual folder structure is the following:

Additionally I added a "\" on the line where PHPExcel_IOFactory uses In Controller Class:

public function reporteauditoriaAction()
{
    $objPHPExcel = new \PHPExcel();
    $objPHPExcel->createSheet();
    $objPHPExcel->getActiveSheet()->setCellValue('A1', 'Alejin Wbn');
    $objWriter = \PHPExcel_IOFactory::createWriter($objPHPExcel, "Excel2007");
    $objWriter->save("pruebaPhpExcelZend.xlsx"); 
    //$objPHPExcel->disconnectWorksheets();
    //unset($objPHPExcel);
    $consulta= "Reporte Auditoria, Reconocio los Archivos";
    $vista = new ViewModel(array( "consulta"=>$consulta));
    return $vista;        
}
