Abstract

Penelitian tentang pengaruh temperatur dan waktu putar terhadap sifat optik lapisan tipis ZnO yang dibuat dengan metode sol-gel spin coating telah dilakukan.  Penelitian dilakukan dengan variasi suhu 400oC, 500oC dan 600oC dengan waktu putar 4 menit dan 6 menit pada kecepatan 2000 rpm.  Uji UV-Vis dan XRD  digunakan untuk mempelajari sifat optik dan struktur.  Nilai minimum  bandgap sebesar 5,5 eV diperoleh pada lapisan tipis yang dideposisi dengan waktu putar 6 menit dan suhu annealing 600oC Karakterisasi UV-Vis menunjukkan absorbsi paling besar 0,944 diperoleh pada lapisan tipis  yang terdeposisi dengan waktu putar 4 menit dan suhu annealing 400oC, Hasil XRD yang  menunjukkan penambahan suhu menyebabkan menurunnya ukuran kristal. 

Kata kunci : sol gel spin coating dan bandgap.
