✦ Synopsis

The structure and radiative properties of aluminophosphate glasses in the system KzO-AI203-P205 and BaO-AI203-P205 were investigated. The structural changes in glasses with the addition of alumina were investigated by using FTIR spectroscopy and NMR spectroscopy. In the case of the K20-AIzO3-P205 glasses, the aluminium atoms were mainly octahedrally coordinated and acted as network modifiers. The decrease in the spontaneous emission rate of K20-AI203-P20~ glasses was due to the tightening of chains in terms of the addition of alumina to the glasses. The increase in effective linewidth was probably due to the increase of end groups in the glasses. In the case of BaO-AI203-P20~ glasses, the addition of alumina had little effect on the radiative properties, probably due to the small structural change which occurred on its addition.
