Various attempts have been made to solve problems of abundant solid wastes in big cities. One approach is the utilization of domestic waste to make composite materials, such as particle board. To increase the attractiveness of the product in this study we develop prototypes of statues using composites of domestic solid wastes and then coated the statues using carboneus phosphor material to produce artistic color under ultraviolet illumination. The composite materials were derived from domestic waste such as leaves, paper, and plastics as a filler and polyvinil acetate as a matrix. The coated material was a luminescent colloidal carbon particles that have been synthesized from urea ((NH2)2CO) and citric acid (C6H8O7) using a simple heating method. The colloidan carbon emits a luminescence peak at around 457 nm (blue color) under UV illumination. The produced statue from the domectic wastes composites we simply coated by a mixture of epoxy resin and phosphor material. Under UV light, the statue surface shows a bluish white luminescence.

“…The process of determining the size of the nanoparticles using a diffraction grating and image processing-based optical spectrometer is shown in figure 2. The CNPs were synthesized using citric acid and urea (as a carbon and fuel source, respectively) held at 190 °C for 2 h to obtain black powder carbon [10]. The solution of CNPs was prepared by dispersing this carbon powder in water at several carbon concentrations (g l −1 ) using the dilution method.…”

“…Carbon nanoparticles (CNPs) are a type of semiconductor nanoparticle that have several unique characteristics, such as relatively uniform size, dispersibility in water, superior optical properties, and a facile synthesis method [8][9][10]. Moreover, accurate measurement of CNP concentration and particle size has an important role in the development of carbon applications in low-cost research in educational laboratories.…”

In this paper, we report on a homemade optical spectrometer using diffraction grating and image processing techniques. This device was designed to produce spectral images that could then be processed by measuring signal strength (pixel intensity) to obtain the light source, transmittance, and absorbance spectra of the liquid sample. The homemade optical spectrometer consisted of: (i) a white LED as a light source, (ii) a cuvette or sample holder, (iii) a slit, (iv) a diffraction grating, and (v) a CMOS camera (webcam). In this study, various concentrations of a carbon nanoparticle (CNP) colloid were used in the particle size sample test. Additionally, a commercial optical spectrometer and tunneling electron microscope (TEM) were used to characterize the optical properties and morphology of the CNPs, respectively. The data obtained using the homemade optical spectrometer, commercial optical spectrometer, and TEM showed similar results and trends. Lastly, the calculation and measurement of CNP size were performed using the effective mass approximation (EMA) and TEM. These data showed that the average nanoparticle sizes were approximately 2.4 nm and 2.5 ± 0.3 nm, respectively. This research provides new insights into the development of a portable, simple, and low-cost optical spectrometer that can be used in nanomaterial characterization for physics undergraduate instruction.

“…This research will be carried out the use of carbon nanoparticles to determine the effect on the improvement of the efficiency of the distillation process based on the warming by the sunlight. Carbon nanoparticles was used based on the properties of sunlight absorption which is good enough and also can absorb almost the entire wavelength range from UV to visible light (Mahen, Nuryadin, Iskandar, Abdullah, & Khairurrijal, 2014). Therefore the use of carbon nanoparticles are expected to increase the efficiency of absorption of sunlight in the distillation process based on warming of the sunlight.…”

Carbon nanoparticles (C-Dots) were synthesized using citric acid and urea as carbon and fuel source, and combustion reaction methods. The absorption spectral and morphology particles of C-Dots were investigated. The morphology describes the synthesis of small (<1 ?m) and monodispersedC-Dots. Thus, the C-Dots solutions has absorption spectral range of about 86% at visible light spectral. This study suggests that the as-prepared carbon nanoparticles (C-Dots) with particle size and absorption spectral tunability might be utilized as solar energy absorber material.Karbon nanopartikel (C-Dots) disintesis menggunakan asam sitrat dan urea sebagai sumber karbon dan bahan bakar, melalui reaksi pembakaran sederhana. Spektrum absorpsi dan morfologi partikel C-Dots diinvestigasi menggunakan UV-Vis Spectrometry dan analisis SEM. Hasil SEM menunjukan bahwa morfologi partikel C-Dots sangat kecil (<1 ?m) dan seragam. Selain itu, larutan C-Dots memiliki spektrum absopsi pada rentang sekitar 86% pada daerah cahaya tampak. Hasil studi ini menunjukan bahwa karbon nanopartikel (C-Dots) dengan ukuran partikel dan spektrum absorpsi yang dapat diatur, sehingga dapat digunakan sebagai material penyerap sinar matahari.
