The LaPO4:Yb,Er nanocrystals with the smaller particle size than 10nm were prepared by solution-based reaction at around 200℃ and their properties were characterized. The prepared nanocrystals are single-phased and present the monazite structure. The surface of nanocrystals is capped with with the solvent molecules used in the synthesis reaction, which possibly prevents them from agglomerating. For possible application as optical amplification materials in telecommuncations, the LaPO4:Yb,Er nanocrystals were successfully incorporated into the sol-gel organic/inorganic hybird matrix up to 30% without phase separation. The composite films shows strong luminescence intensity in the near infrared region around 1540nm, due to the effective energy transfer from Yb3+ to Er3+. The propagation loss of the films has a tendensy to be incrsased with increasing the content of the nanocrystals.
