Abstract: A red phosphor that has optical characteristics and durability under high-temperature and high-humidity environments, and a method for producing the same. The red phosphor includes a Mn-activated complex fluoride represented by the following general formula (1) and bismuth: A2MF6:Mn4+??(1) wherein A represents at least one alkali metal element selected from the group consisting of lithium, sodium, potassium, rubidium and cesium, and M represents at least one tetravalent element selected from the group consisting of silicon, germanium, tin, titanium, zirconium and hafnium.

Abstract: A planter and stand assembly includes a stand having a sidewall surrounding a hollow region and tapered between a first end of the sidewall and a second end of the sidewall, the stand having a first opening at the first end and a second opening at the second end, the first opening larger than the second opening, and the stand having a first stand support surface at the first end and a second stand support surface at the second end; and a planter having a first planter support surface sized to radially overlap with the first stand support surface and rest thereon in a first configuration in which the first stand support surface faces upward and a second planter support surface sized to radially overlap with the second stand support surface and rest thereon in a second configuration in which the second stand support surface faces upward.
