Abstract

Telah dilakukan sintesis dan karakterisasi lapisan tipis opal menggunakan metode deposisi horizontal dengan penambahan vibrasi. Sintesis dilakukan pada suhu ruang dengan variasi kecepatan vibrasi 0, 1000, 1250, dan 1500 rpm menggunakan magnetic stirrer. Karakterisasi dilakukan menggunakan Mikroskop Optik, SEM (Scanning Electron Microscopy) dan Spektrofotometer UV-Vis. Hasil mikroskop optik menunjukkan permukaan sampel dengan vibrasi lebih homogen dan tebal dibandingkan tanpa vibrasi. Hasil SEM menunjukkan lapisan multilayer terbentuk pada sampel vibrasi dengan kecepatan putaran 1500 rpm. Spektrum absobsi spektrofotometer UV-Vis menunjukkan nilai absorbansi maksimum tertinggi pada panjang gelombang 564 nm dengan nilai absorbansi 0,1526. Semakin tinggi kecepatan vibrasi yang digunakan, semakin tinggi nilai absorbansi maksimum dan semakin tinggi nilai FWHM.
