The　preparation　of　high　performance　upconversion　luminescence　materials　with　stronger　shortwave　emissions　is　still　a　challenge.　In　this　work,　the　feature　of　hexagon　circles　sublattice　structure　of　tetragonal　LiYF4　was　revealed,　and　the　sublattice　level　energy　clusters　of　4　Yb3+-1Tm3+　were　constructed　by　the　substitution　of　70　mol%　Yb3+　for　Y3+　in　tetragonal　LiYF4　matrix.　The　sensitizing　ions　concentration　quenching　was　inhibited　by　the　hexagon　circles　sublattice　structure,　and　the　upconversion　luminescence　was　dramatically　enhanced,　especially,　the　UV　band　emission　was　enhanced　about　20　times　and　the　intensity　ratio　of　UV　to　blue　emissions　was　improved　about　10　folds　under　the　excitation　power　density　of　0.230　W/cm2.　Photon　numbers　of　upconversion　emissions　obviously　decreased　with　the　increasing　of　sublattice　level　energy　clusters　that　the　upconversion　process　of　three　photons　was　changed　to　two　steps　of　two　photons　process.　The　upconversion　luminescence　mechanism　of　sublattice　energy　cluster　construction　was　system　investigated.　The　material　with　high　performance　of　UV　and　blue　UC　luminescence　can　be　a　well　candidate　for　the　applications　of　photodynamic　therapy　and　photocatalytic,　etc.　The　work　may　be　an　inspiration　for　high　efficient　UC　luminescence　materials　design　and　preparation.　©　2019
