##submission.downloads##
Maqolada Er³⁺ va Yb³⁺ ionlari bilan dopirlangan NaYF₄ kvant nuqtalarini solvotermal usuli bilan sintez qilish natijalari keltirilgan. Zarrachalar hajmi nurni dinamik yorug'lik tarqalishi metodi (DLS) bilan aniqlandi: diametri ~1,3 nm bo‘lgan nanozarralar va taxminan 3,8 × 10⁵ nm agregatlar aniqlandi. Optik tahlil Yb³⁺ → Er³⁺ energiyaning samarali uzatilishi natijasida kelib chiqqan maksimal 582 nm bo'lgan kuchli anti-Stoks emissiyasini ko‘rsatdi. Sariq emissiyaning mavjudligi olingan materiallarni yashil va qizil chiziqlar ustunlik qiladigan odatiy NaYF₄:Yb/Er tizimlaridan ajratib turadi.
