The present invention discloses a red light and near-infrared light-emitting material and a light-emitting device. The red light and near-infrared light-emitting material contains a compound represented by a molecular formula, xAO&#xb7;yInO&#xb7;bRO, wherein the element A is Sc and/or Ga; the element R is one or two of Cr, Yb, Nd or Er and necessarily includes Cr; and 0.001&#x2264;x&#x2264;1, 0.001&#x2264;y&#x2264;1, 0.001&#x2264;b&#x2264;0.2, and 0.001&#x2264;b/(x+y)&#x2264;0.2. The light-emitting material can be excited by a technically mature blue light source to emit light with a high-intensity wide-spectrum or multiple spectra. Compared with existing materials, the light-emitting material has higher luminescent intensity. The light-emitting device uses an LED chip to combine an infrared light-emitting material and a visible light light-emitting material. In this way, the same LED chip can emit near-infrared light and visible light at the same time, which greatly simplifies the packaging process and reduces the packaging cost.
