摘要:The invention relates to synthesis of nanoparticles from hazelnut husk extract by green synthesis with high efficiency. Use of chemical is limited in the present invention and therefore the synthesis of nanoparticles is provided by green chemistry in the present invention. Said hazelnut may be Corylus and said hazelnut husk may be cob or shell of the hazelnut. In an embodiment of the invention said Corylus may be Colyrus colurna, Corylus americana Corylus avellana, Corylus avellana var. Avellana, Corylus avellana var. Pontica, Corylus chinensis, Corylus colchica, Corylus × colurnoides, Corylus cornuta, Corylus cornuta ssp. californica, Corylus cornuta ssp. cornuta, Corylus fargesii, Corylus ferox, Corylus ferox var. ferox, Corylus ferox var. thibetica, Corylus heterophylla, Corylus heterophylla var. heterophylla, Corylus heterophylla var. sutchuensis, Corylus jacquemontii, Corylus maxima, Corylus potaninii, Corylus sieboldiana, Corylus sieboldiana var. mandshurica, Corylus sieboldiana var. sieboldiana, Corylus wangii, Corylus wulingensis or Corylus yunnanensis.

摘要:The present invention relates to luminescent compounds of lanthanide/Yb doped bismuth silicate that present a crystalline structure and are characterized by non-linear optical properties, particularly photon up-conversion following IR or NIR excitation. Furthermore, the present invention describes several synthesis routes for producing said compounds in different form (e.g. particles, core-shell particles, bulk crystal), dimension (e.g. nanoscale or microscale) and crystalline structure, which result in tunable optical properties in view of a specific application. Particularly, there are disclosed Er/ Yb, Ho/Yb, Tm/Yb doped bismuth silicate nanoparticles that emit up-conversion light of the three basic colors (RGB). As said compounds are non-cytotoxic and present attractive optical properties, they find a wide range of applications, both industrial (e.g. lighting, solar energy, anti-counterfeiting) and biomedical (e.g. drug delivery, bio-imaging, nanomedicine).
