We experimentally demonstrate high-speed visible light communication (VLC) and high-quality solid-state lighting (SSL) using polymethyl-methacrylate-doped phosphor film based on cesium lead bromide quantum dot ( CsPbB r 3 -QD) and potassium fluorosilicate K 2 Si F 6 : M n 4 + , which is excited by a blue gallium nitride laser diode. A 1.6 Gbps data rate is achieved by employing a non-return-to-zero on–off keying modulation scheme. The measured bit error rate of 2.7 × 10 − 3 adheres to the standard threshold ( 3.8 × 10 − 3 ) of forward error correction. Moreover, the generated white-light source has a high color rendering index of 93.8 and a correlated color temperature of 4435 K, and it exhibits a Commission Internationale de l’Eclairage (CIE) 1931 chromaticity coordinate at (0.3556, 0.3520), which is close to the ideal CIE value of white light (0.3333, 0.3333). This work opens up exciting possibilities for future high-speed indoor VLC and high-quality SSL.

AbstractA long term field study using permanent layout was conducted to investigate the effect of P application (0, 40, 80, 120 kg P2O5 ha ) for both DSR and wheat crop were kept in main plots and P application was in sub plots. Data on tillering, plant height, panicle length, paddy and straw yields was collected from both rice and wheat crops. On an average of two year DSR data, maximum tillers (16), panicle length (27), grain panicle -1 (89) and paddy yield (2.75 t ha -1) was produced with P application @ 80 kg P2O5 ha -1 along with CR incorporation, which was considerably better (13%) than that of P application @ 120 kg P2O5 ha -1 without CR incorporation. A significant increase (22% and 19%) over control in paddy and wheat grain yields, respectively was observed with 80 kg P2O5 ha -1 application along with CR incorporation. Overall, continuous two year CR incorporation further increased 9% paddy during the follow up year of crop harvest as compared to without CR incorporation. Maximum wheat grain yield (2.84 t ha -1 ) was harvested with 80 kg P2O5 ha -1 + CR and was significantly higher than grain yield (2.68 t ha -1 ) receiving 120 kg P2O5 ha -1 without CR incorporation. Higher concentrations of P, K and Ca 2+ in plant tissues (rice and wheat) were found where P was applied @ 80 kg P2O5 ha -1 along with CR incorporation or 120 kg P2O5 ha -1 alone while Na + and Mg 2+ concentration decreased with increasing the rate of P. Overall, an increasing trend in paddy yield of DSR was observed with increasing the rate of P application without CR incorporation during both the cropping years.
