Samarium ions (Sm+3), a rare-earth element, have a significant optical emission within the visible spectrum. PMMA samples, mixed with different ratios of SmCl3.6H2O, were prepared via the casting method. The composite was tested using UV-visible, photoluminescence and thermogravimetric analysis (TGA). The FTIR spectrometry of PMMA samples showed some changes, including variation in band intensity, location, and width. Mixed with samarium decreases the intensity of the C-O and CH2 stretching bands and band position. A new band appeared corresponding to ionic bonds between samarium cations with negative branches in the polymer. These variations indicate complex links between the Sm+3 ion and oxygen in the ether group. The optical absorption increased within the visible spectrum while the emission increased. The TGA analysis showed more thermal stability for samples mixed with Sm, where the degradation point shifted to higher energy and with less mass loss in the decomposition region. A triplet band were performed in the emission curve for PMMA reinforced with Sm+3. The outcomes show the possibility of using samarium-enhanced PMMA in optical applications..
