“…Tellurite glasses can also reduce the sintering temperature down to 520°C, 56,[122][123][124][125][126][127][128][129][130][131][132][133][134] but they also have visible absorption and the high production cost of TeO 2 , which hampers mass production. Borate 60,113,114 and phosphate [115][116][117][118][119] glasses can be sintered below 600°C but they have weak chemical stability against moisture. Low sintering temperature below 400°C has been achieved with oxyfluoride glass based on SnO-SnF 2 -P 2 O 5 [135][136][137][138] and Bi 2 O 3 -B 2 O 3 .…”

Phosphor-in-glass (PiG) is a mixture of a transparent glass and ceramic phosphors and has been recently commercialized for its various advantages as an inorganic color converter for white light emitting diodes (wLEDs). Since the successful demonstration of the wLED and its improved stability over the conventional phosphors in silicon or organic resins, extensive studies have been reported to improve its color conversion and resultant LED properties, such as luminescence efficacy, chromaticity, correlated color temperature and color gamut, as well as its long term stability. Various attempts have also been made to fabricate a PiG structure and to extend its applications. This study reviews the recent progress of PiG and discusses various approaches that have been proposed to overcome the technical issues related to PiG.

“…Concerning the TIMs’ manufacture, the additive-type patterning of screen-printing technology [23,24,25] is widely used for EGN-based composites. Thermally cured and screen-printed EGN/SNP-embedded polydimethylsiloxane (PDMS) TIMs and ball milling was investigated in [26,27].…”

Ball-Milled Recycled Lead-Graphite Pencils as Highly Stretchable and Low-Cost Thermal-Interface Materials

et al. 2018

A simple and sustainable production of nanoplatelet graphite at low cost is presented using carbon-based materials, including the recycled lead-graphite pencils. In this work, exfoliated graphite nanoplatelets (EGNs), ball-milled exfoliated graphite nanoplatelets (BMEGNs) and recycled lead-graphite pencils (recycled 2B), as well as thermally cured polydimethylsiloxane (PDMS), are used to fabricate highly stretchable thermal-interface materials (TIMs) with good thermally conductive and mechanically robust properties. Several characterization techniques including scanning electron microscopy (SEM) and thermogravimetric analysis (TGA) showed that recycled nanoplatelet graphite with lateral size of tens of micrometers can be reliably produced. Experimentally, the thermal conductivity was measured for EGNs, BMEGNs and recycled 2B fillers with/without the effect of ball milling. The in-plane thermal conductivities of 12.97 W/mK (EGN), 13.53 W/mK (recycled 2B) and 14.56 W/mK (BMEGN) and through-plane thermal conductivities of 0.76 W/mK (EGN), 0.84 W/mK (recycled 2B) and 0.95 W/mK (BMEGN) were experimentally measured. Anisotropies were calculated as 15.31, 15.98 and 16.95 for EGN, recycled 2B and BMEGN, respectively. In addition, the mechanical robustness of the developed TIMs is such that they are capable of repeatedly bending at 180 degrees with outstanding flexibility, including the low-cost renewable material of recycled lead-graphite pencils. For heat dissipating application in high-power electronics, the TIMs of recycled 2B are capable of effectively reducing temperatures to approximately 6.2 °C as favorably compared with thermal grease alone.
