“…The average lifetimes of the Ba 2 Sr 1‐x WO 6 : xSm 3+ (x = 0.5, 1, 3, 5, 7, 9 mol%) samples are 1.819, 1.722, 1.599, 1.338, 1.149 and 1.057 ms, respectively. The variation tendency for the influence of the Sm 3+ content on decay time remains consistent with that for the influence of the Sm 3+ content on the PL [34].…”

The predominant method for pest control has been the use of pesticides, which have been shown to have detrimental effects on soil, freshwater, and crop quality. Therefore, the development of novel and sustainable crop protection strategies has become increasingly imperative. In this study, a novel orange–red emitting Ba2SrWO6: Sm3+ phosphor was synthesized using the high‐temperature solid‐state reaction. Under ultraviolet excitation, the phosphors showed obvious emission peaks at 575, 614, and 662 nm. The Ba2SrWO6: Sm3+ was used to fabricate a fluorescence film with polydimethylsiloxane (PDMS), and attracted twice as many insects as the blank control group under 365 nm ultraviolet light. This material holds great potential as a fluorescent agent for insect trapping in the pest control fields of tea, cotton, eggplant, rice, potato, grape, and other agricultural industries. Our findings provide an eco‐friendly approach to pest management for the increment of food production.

“…These phenomena indicate that the ITO-based perovskite PMPI 3 material is completely decomposed after heating at 140°C. Combined with the above experimental results, it is found that the nanoperovskite PMPI3 film with ITO as the substrate, and it is more prone to thermal decomposition than thin films on glass substrates [ 14 ].…”

In order to overcome the problem of long-term stability of perovskite solar cells, the author proposes a method to study the effects of nanosemiconductor materials on the thermal stability of solar cells. In this method, n = 3 and n = 1 (C6H5(CH2)2NH3)2(CH3NH3)n-1Pbn I3n+1 two-dimensional nanoperovskite films were investigated on glass substrates and indium tin oxide (ITO) substrates, respectively, on the thermal stability. Experimental results show that the glass-based nanoperovskite PMPI3 film was partially decomposed into PbI2 after being heated at 160°C. When the temperature reaches 180°C, the film is completely decomposed into PbI2, and the perovskite PMPI3 film with ITO as the substrate is completely decomposed into PbI2 when the heating temperature reaches 140°C. The charge transfer between the perovskite film and the substrate is the physical reason for its easier thermal decomposition on the ITO substrate. Suggestions for improving the thermal stability of perovskite solar cell devices are given from the aspects of device design and fabrication process.

“…These results triggered the nonradiative loss of Sm 3+ and compelled the Sm 3+ to pass through an expansion during the excitation stage, which improved the 4f–4f transitions in the excitation process, and the value could be larger than that of CTB .

The strategy to enhance phosphor stability against thermal quenching and moisture conditions will contribute to controlling the feature of phosphor-converted white-light-emitting diodes (pc-WLEDs). Herein, an effective strategy is achieved with the incorporation of Sm 3+ ions, and a robust reddish-orange emission (no thermal quenching up to 498 K) is obtained based on Ba 3 LaNb 3 O 12 as a host. In light of excitation by near-ultraviolet irradiation at 408 nm, Ba 3 LaNb 3 O 12 :Sm 3+ gives rise to a typical signal ascribed to the 4 G 5/2 → 6 H J/2 (J = 5, 7, 9, and 11) transitions of Sm 3+ ions. The concentration quenching effect is observed when the Sm 3+ content exceeds 10%, and the quenching mechanism is caused by electronic dipole−dipole interactions. Based on the narrow emission curves, a very high color purity (92.4%) could be recorded. The Sm 3+ substitution at the Ba 2+ /La 3+ site leads to a rigid structural lattice and abundant electron-trapping centers for the Sm 3+ ions, which will be responsible for the zero-thermal-quenching phenomenon. In addition, oleic acid (OA) is selected to form a hydrophobic covering surface structure to protect Ba 3 LaNb 3 O 12 :Sm 3+ , which can assist in improving the moisture resistance. The most favorable parameters concerning the warm-light emission (a high general color rendering index, Ra, of 85.7 and a low correlated color temperature, CCT, of 4965 K) can be achieved in pc-WLEDs containing an OA-modified sample. Moreover, its luminous efficiency, LE, can maintain 82.9% of its initial value after 120 h under controlled environmental conditions of 85 °C and 85% humidity. These results pave a new way to optimize the sample as a potential candidate for red-emitting materials.
