A`yun, Qurratu (2016) Sintesis dan Karakterisasi Lapis Tipis Timbal Zirkonat Titanat Menggunakan Prekursor Zirkonium Nitrat dan Penstabil Asetil Aseton dengan Variasi Pemeraman. Sarjana thesis, Universitas Brawijaya.
Abstract
Pada penelitian ini telah dilakukan penelitian tentang pengaruh modifikasi pelarut dalam sintesis PZT dengan metode sol-gel, dan pengaruh variasi pemeraman terhadap struktur kristal, morfologi, komposisi, ukuran kristal serta fase rhombohedral dan tetragonal lapis tipis timbal zirkonat titanat (PZT). Proses pembuatan prekursor PZT dilakukan dengan metode sol-gel menggunakan larutan penstabil asetil aseton dan penumbuhan lapis tipis PZT di atas substrat silikon (100) dengan metode spin coating. Pendeposisian prekursor timbal zirkonat titanat dilakukan dengan kecepatan putar 2000 rpm. Hasil analisis DTA-TGA menunjukkan puncak kristalinitas PZT pada temperatur 600,68 oC. Proses anil lapis tipis PZT pada suhu 600 oC selama dua jam. Karakterisasi data menggunakan instrumen difraktometer sinar-X pada 2θ 20o-80o dengan λ kα 1,540598 Å. Hasil XRD menunjukkan bahwa terbentuk lapisan perovskit PZT dengan orientasi bidang kristal (100), (101), (110), (111), (002), (200), (201), (210), dan (022) yang mengindikasikan kristal yang terbentuk adalah polikristalin. Pemeraman dengan pengadukan memiliki ukuran kristal terbesar yaitu sebesar 61,888 nm dengan fase rhombohedral dan tetragonal tertinggi yaitu sebesar 68,14 %.
English Abstract
This research was conducted to understand the effects of modification of the solvent in the synthesis of PZT by sol gel method, and the effects of aging variation in the crystal structure, morphology, composition, crystallite size, as well as the rhombohedral and tetragonal phases of lead zirconate titanate (PZT) thin film. The making progress of PZT precursor was done by sol-gel method using a stabilizer solution such as acetyl acetone and the growth of PZT thin film on silicon substrate (100) was done by the spin coating method. The deposition of lead zirconate titanate precursor was done with the rotational speed of 2000 rpm. The Differential Thermal Analysis-Thermal Gravimetric Analysis (DTA-TGA) analysis resulted a crystallinity peak of PZT at the temperature of 600,68 oC. PZT thin film was annealed at 600 oC for two hours. The characterization was done by using X-Ray Diffraction instrument at 2θ 20o-80o with λ kα 1.540598 Å and resulted in showing that the PZT perovskite film was formed with the crystal planes orientation of (100), (101), (110), (111), (002), (200), (201), (210), and (022) which indicating that the crystals formed were polycrystalline. The aging treatment using stirrer had the largest crystallite size that is equal to 61.888 nm with the highest percentage of rhombohedral and tetragonal phase is equal to 68.14 %.
