Keywords:wavelength conversion sheet, agriculture use

Wavelength conversion sheets dispersed with chemically stable inorganic phosphor have been developed for agriculture and horticulture. Far-red phosphor Al₂O₃:Cr was employed as the phosphor, since it has advantages of low price and is expected to enhance the photomorphogenesis. Cultivation results for some plants using the wavelength conversion sheets will be reported.
