In　this　paper,　an　efficient　recovery　of　rare　earth　elements　from　waste　fluorescent　phosphors　has　been　reported　and　the　novel　process　of　alkali　fusion　and　acid　leaching　has　been　proposed.　The　experimental　results　have　shown　that　the　key　for　efficient　recycling　is　the　complete　dissolution　of　waste　fluorescent　phosphors.　The　Na2O2-to-waste　mass　ratio,　calcination　temperature　and　reactive　time　play　considerable　roles　in　rare　earth　elements　extraction　during　the　alkali　fusion　process.　The　optimal　conditions　in　terms　of　temperature,　time　and　Na2O2-to-waste　mass　ratio　are　650　A　degrees　C,　15　min　and　2:1,　respectively,　under　which　more　than　99.5　%　rare　earth　elements　are　extracted.　The　possible　reaction　mechanism　of　alkali　fusion　has　been　proposed.
