Luminescence properties of SrB4O7:Sm2+ for light conversion agent

Investigation of SrB4O7:Sm2+ as a Multimode Temperature Sensor with High Sensitivity

“…All chemicals were analytical grade and were used as received without further purification. The solid-state reaction method 28 was used for the synthesis of SrB 4 O 7 :5% Sm 2+ . In the process of preparation, SrCO 3 , H 3 BO 3 , and Sm 2 O 3 were used as the starting materials in the proper stoichiometric ratio.…”

“…SrB 4 O 7 was recently reported as a host lattice in applications such as light conversion 28 and pressure sensing. 29 SrB 4 O 7 has excellent thermal and chemical stability, 28 and the tetrahedral structure of the BO 4 can stabilize divalent rare earth ions, even at high temperature in an oxidizing atmosphere. 28 These characteristics make SrB 4 O 7 a good host to incorporate Sm 2+ for wide-range temperature-sensing applications.…”

Research Progress of Light Wavelength Conversion Materials and Their Applications in Functional Agricultural Films

“…In recent years, it has attracted extensive attention and has been actively developed. An agricultural film added with a light conversion agent is called a light conversion film, which can convert the lower active wavelength band in photosynthesis to the higher active wavelength band (400-700 nm), in turn changing the ultraviolet (280-380 nm) and yellow green (510-580 nm) wavelengths of sunlight into the blue-violet (400-480 nm) and red-orange (600-700 nm) wavelengths required for plant photosynthesis, improving crop yield and quality [11][12][13][14][15][16][17][18][19][20]. Therefore, based on the research on light conversion agents at home and abroad in recent years, this paper classifies the types of light conversion agents and their preparation methods, summarizes the applications for light conversion films in plants, and predicts the future development directions for light conversion agents and light conversion films.…”

Huge enhancement of Sm2+ emission via Eu2+ energy transfer in a SrB4O7 pressure sensor

“…Moreover, the similar ionic radii of the dopant and host ions (R Eu 2+ = 1.39 Å, R Sm 2+ = 1.41 Å and R Sr 2+ = 1.40 Å) provide less lattice distortion of the synthesized crystals. [44][45][46][47] Many works have focused on the synthesis of different compounds doped with Sm 2+ and other trivalent lanthanide ions, i.e. Ce 3+ , Er 3+ , Tm 3+ , etc., and their use for pressure sensing applications.…”
