Abstract

Nanopartikel ZnO disintesis dengan metode sol-gel menggunakan Li2CO3 sebagai pendoping dengan variasi konsentrasi 0, 4, 6 dan 8% mol. Hasil sintesis dikarakterisasi dengan difraksi sinar X (XRD) untuk menentukan ukuran dan stuktur kristal, sedangkan UV-Vis untuk menentukan lebar celah pita energi.  Hasil XRD menunjukan bahwa stuktur kristalnya hexagonal dan ukuran kristal yang didapat adalah 28,33; 32,68; 60,69 dan 60,72 nm. Energi gap terkecil berada pada saat konsentrasi 8% mol yaitu 3,09 eV. Nanopartikel ZnO yang disinari lampu UV berwarna kuning.
