摘要：光子晶体是由两种具有不同介电常数的材料在一维、二维、或三维方向上周期性排列而成的一种人工结构材料。多孔氧化铝模板(PAA)中的孔洞是具有排列整齐，大小均一优点的纳米级管道，是一种可以利用简易工艺制备光子晶体的完美材料。纳米氧化锌(ZnO)也被广泛应用，因其为一种重要的宽禁带直接带隙半导体发光材料。纳米氧化锌胶体是以溶胶—凝胶法制备而成，并将其注入到多孔氧化铝模板的纳米孔道中去，形成了ZnO/PAA复合电致发光器件，这种器件具备了制作容易、工艺简单、用途广泛、成本低廉的优点，在电致发光及光电转换与显示的涉及领域中，应用前景广大，值得进一步研究。

　　　本文介绍了纳米氧化锌材料、光子晶体、多孔氧化铝模板的基本概念和发展情况，并用溶胶—凝胶法在PAA上注入了ZnO。通过对样品的XRD测试，表明是六方晶相氧化锌微粒。随着退火温度的升高，纳米ZnO粒子粒径缓慢增大；在500℃-700℃之间退火时，500℃后ZnO结晶性比较好，纳米ZnO粒子粒径与退火温度成直线关系，并随退火温度的升高而增加。

Abstract: The photonic crystal is a synthetic structure material，which has a periodic arrangement of two kinds of materials with different dielectric constant on one, two or three dimensions. In photonic crystal, the transmission of light with a certain wavelength is limited. Theoretically, through adjusting the prime parameters of the photonic crystal and limiting the transmission of light to a certain direction, we can accomplish the purpose of luminescence enhancement. On the Porous Anodized Alumina(PAA), nano-sized pores are arranged periodically, so the PAA is a perfect material to prepare a photonic crystal with a simple and easy technology.Zinc dioxide as a wide gap light-emitting semiconductor, is widely interested by researchers. We prepare ZnO colloid by sol-gel method, inject it into the nano-holes of PAA and form a ZnO/PAA compound electroluminescent device. This device has the advantage of easy production, low price and wide use. It has great application possibilities in the area of electro-luminescence and electro-photo-display.

　　In this paper the basic concept and the development of photonic crystal, PAA and ZnO nano material are introduced and the process of the experiment is presented. Through the test of a sample XRD, indicates that it is The six crystal directionzinc oxide particles. Along with the  increasing of annealing temperature, nanometer ZnO particle size increases slowly; at 500 ℃-700℃ annealing, ZnO  crystal is better is better after 500 ℃, nanometer ZnO particle size and the annealing temperature in linear relation, and  increased with increasing annealing temperature increase.
