Cadmium sulfide thin film nanostructures with various surface morphologies were synthesized using chemical bath deposition method (CBD) by varying bath temperature. Samples deposited at room temperature shows surface morphology similar to ‘seaweed’ pattern that crystallized in cubic structure, whereas those deposited at higher temperatures exhibit ‘honeycomb’ like surface pattern with hexagonal crystal structure. HRTEM images of the honeycomb structure shows that, nanowalls consist of CdS nanoparticles embedded with cadmium hydroxide just like ‘plum in pudding’. An improvement in conductivity and photosensitivity observed with increase in bath temperature. Photoluminescence measurements show that there are five emission peaks falls in green, red and infrared bands. The intensity of photoluminescence emission in the green band region found to be increased on thin films that deposited at elevated temperatures. Unique honeycomb like structures observed at 65 °C, shows comparatively high performance in structural and optoelectronic properties give it a slight edge in optoelectronic application.

使用化学浴沉积法（CBD），通过改变浴温来合成具有各种表面形态的硫化镉薄膜纳米结构。在室温下沉积的样品显示出类似于以立方结构结晶的“海藻”图案的表面形态，而在较高温度下沉积的样品则显示出具有六方晶体结构的“蜂窝”状表面图案。蜂窝结构的HRTEM图像显示，纳米壁由嵌有氢氧化镉的CdS纳米颗粒组成，就像“布丁中的李子”一样。随着浴温的升高，电导率和光敏性得到改善。光致发光测量表明，在绿色，红色和红外波段中有五个发射峰。发现在高温下沉积的薄膜上，绿色带区域中的光致发光发射强度增加。在65°C下观察到的独特蜂窝状结构显示出较高的结构和光电性能，使其在光电应用中略有优势。
