Abstract
In the natural environment, light is an indispensable factor affecting plant growth, and plant growth phosphor-converted light emitting diodes (pc-LED) for an artificial light source can play a role in accelerating photosynthesis and development of indoor plants. In this work, we obtained a series of red-emitting phosphors Bi3+, Mn4+ co-doped 4SrO‧7Al2O3, which were synthesized by sol-gel method, and red-light emission enhancement through doping of sensitizer Bi3+. The energy transfer process and mechanism were analyzed by photoluminescence spectra and fluorescence lifetime. And it thermal stability was 58.50% at 423 K, which show that the phosphor has good photostability. The red and blue dual emission of the packaged LED device can better match the absorption spectra required by chlorophyll a, b and phytochrome PR of plants. Therefore, the as-prepared phosphor has a certain development prospect in the application of plant growth LEDs.
