“…Beyond the glass melting temperature the sample would begin to melt or degrade, which also showed that the heat flow curve was significantly decreased. In pervious study [15], the TGA result of PiG showed that the glass melting temperature is 519°C. Figure 4(a) showed that the first peak of the blue curve showed an endothermic peak at the around of 510°C, which was the glass melting temperature of PiIS.…”

“…Thermal stability was defined as the ability of the phosphor-in encapsulant to resist the action of heat and to maintain its optical properties, such as luminous flux, international commission on illumination (CIE), or correlated color temperature (CCT) at a limited temperature range [4][5][6][7]15]. In order to realize the thermal analysis of the PiIS, PiOS, and PiG, the thermogravimetric analysis (TGA) was investigated.…”

A high reliability and luminance of color wheel in laser light engine (LLE) employing novel phosphor-in-inorganic silicone (PiIS) fabricated at low temperature of 180°C for laser projector applications is presented and demonstrated for the first time. Yellow (Y₃Al₅O₁₂:Ce³+) and green (Lu₃Al₅O₁₂:Ce³+) phosphors were uniformly mixed by inorganic silicone, organic silicone, and glass to fabricate as a phosphor color wheel. The PiIS based color wheels showed better thermal stability than the phosphor-in-organic silicone (PiOS) about 3-7 times less lumen loss and 7-8 times less chromaticity shift under accelerated aging at 350°C for 1008 hours. The advantage of the PiIS fabricated at a low temperature of 180oC enabled achievement of excellent thermal performance, which was similar to the phosphor-in-glass (PiG) fabricated at a high temperature of 680oC. The good thermal stability of the PiIS can be attributed to the high glass melting temperature up to 510oC. Low temperature fabrication, excellent optical performance, and high reliability of the proposed PiIS based color wheels benefit as promising candidates to replace the current PiOS or PIG based color wheels in the LLE modules for the next-generation laser projector applications.

Представлено результати аналізу методів збільшення ємності оптич-них носіїв, у першу чергу, для систем архівного зберігання даних, виз-начено можливості застосування в перспективних типах оптичних носіїв нанокомпозитних матеріалів. Показано, що головним напрямком створення оптичних носіїв з надщільним записом в останні роки стало використання плазмонних резонансів у металевих наноструктурах і реалізація технології ближньопольового запису. Суттєве збільшення щільності запису може забезпечити використання штучної нейронної мережі при відтворенні даних з оптичного носія з нанорозмірними інформаційними елементами.

“…However, it is still a signicant challenge to mitigate the inuence of external environmental factors to obtain water-soluble long aerglow CDs. [1][2][3] Solid materials with a high-efficiency room-temperature long aerglow are widely applied in materials science. However, due to the high concentration of dissolved oxygen in water and free molecular motion, the chromophore is converted from an excited triplet state to a non-radiative state, which leads to instantaneous room-temperature long aerglow loss.…”
