Effect of Silica Nanoparticles on the Photoluminescence Properties of BCNO Phosphor

Fabrication of BCNO-composite thin film phosphors and controlling its thickness

“…A raw material mixture with the mass molar ratio of C/B, N/B, and fraction mass of silica was determined at 20, 3, and 5 % respectively to get homogenous and more luminous BCNO phosphor powder. This is in accordance with the results of studies that have been reported by Nuryadin, et al [12]. The prepared solution was then put in a crucible and heated at 750°C for 30 min in atmosphere.…”

“…The PL spectra of the sample has emission peaks at 502 nm with homogenous bright yellow luminescence. Effect of the silica nanoparticles addition in the luminescence color of the uniform on BCNO particles is strongly associated with a high thermal conductivity at 45.3 J/(mol.K) [12]. The images of thin films samples of BCNOcomposite without (a) and under UV excitation (b) are shown in Fig.…”

“…Recently, Nuryadin et al (2011) succeeded to synthesize BCNO phosphor by addition silica nanoparticles to improve its photoluminescence performance [12]. By adding 5% of silica, BCNO phosphor emitted yellow light (500 nm) and looked more homogeneous than without silica nanoparticles [12].…”

Microwave-Assisted Solid State Synthesis of Red-Emitting BCNO Phosphor and its Characteristics

“…4 In addition, the phosphor had high quantum efficiency (i.e, 79% for photoluminescence (PL) peak at 469 nm under excitation at 365 nm) and the PL peak can be tuned by variation of molar ratio N/B and C/B at precursor. [6][7] In general all BCNO phosphor study aimed to obtain the tunable luminescence of the phosphors at the visible light wavelength region. 5 For instance, our group has synthesized BCNO phosphor with silica nanoparticle, as additive matrix, resulting uniform and relatively high intensity of yellow luminescence.…”
