Abstract
Penelitian ini bertujuan untuk mengetahui cara pembuatan film tipis ZnO dengan menggunakan metode Sol-Gel spincoating. Selain itu, penelitian ini juga bertujuan untuk mengetahui sifat optik film tipis ZnO yang ditumbuhkan diatas permukaan subtract kaca.Pembutan film tipis ZnO dengan metode sol-gel spincoating menggunakan zink Asetat (Zn(CH3COO)2.2H2) sebagai bahan awal. Sol ZnO yang stabil dan homogen dipreparasi dengan melarutkan Zink Asetat Zn(CH3COO)2.2H2O) dalam isopropanol selama 15 menit hingga mencapai suhu 820C dan dipertahankan selama 10 menit dan ditetesi DEA sebanyak 2.41ml. kemudian sol ZnO di dinginkan hingga membentuk Gel. Kemudian dilakukan pelapisan diatas permukaan subtract kaca dengan kecepatan 5000 rpm selama 30 sekon setelah itu di open selama 10 menit Pada suhu 1000C hal ini dilakukan sebanyak 5 kali pelapisan yang bertujuan supaya lapisan tersebut tidak terlalu tipis. Setelah selesai pelapisan, selanjutnya adalah preheating pada suhu 2500C selama 5 jam dan di pertahankan selama 15 menit. Dan hal terakhir adalah postheating pada suhu 5000C selama 5 jam dan dipertahankan selama 15 menit.Hasil XRD dan Uv-Vis Film tipis ZnO dengan konsentrasi 0.6 M memiliki ukuran pertikel ZnO 26.01 nm memiliki band gap 3.34 eV Film tipis ZnO dengan konsentrasi 0,7M memiliki ukuran pertikel ZnO 23.90 nm memiliki band gap 3.00 eV Film tipis ZnO dengan konsentrasi 0.8M memiliki ukuran pertikel ZnO 34.06 nm memiliki band gap 2.86 eV.
